In 2022,Morrill, Charlotte; Gillespie, James E.; Phipps, Robert J. published an article in Angewandte Chemie, International Edition. The title of the article was 《An Aminative Rearrangement of O-(Arenesulfonyl)hydroxylamines: Facile Access to ortho-Sulfonyl Anilines》.Synthetic Route of C5H11NO3 The author mentioned the following in the article:

The discovery of an aromatic rearrangement reaction of O-(arenesulfonyl)hydroxylamines which lead directly to ortho-aminoarylsulfonic acids and ortho-aminobenzenemethanesulfonic acids through formation of a new C-N bond with excellent levels of regiocontrol for the ortho position(s) over all others was reported. The rearrangement was proceeding through an intermol. mechanism and proposed that the regiocontrol observed was the result of attractive non-covalent interactions occurring during the C-N bond-forming step. Importantly, this method was complementary to classical aniline sulfonation in terms of the variously substituted regioisomers that could be obtained and it was also applicable to O-(benzylsulfonyl) hydroxylamines.N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3Synthetic Route of C5H11NO3) was used in this study.

N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3) belongs to anime. Primary amines having a tertiary alkyl group (R3CNH2) are difficult to prepare with most methods but are made industrially by the Ritter reaction. In this method a tertiary alcohol reacts with hydrogen cyanide (HCN) in the presence of a concentrated strong acid; a formamide, RNH―CHO, is formed first, which then undergoes hydrolysis.Synthetic Route of C5H11NO3

Recommanded Product: N-tert-ButoxycarbonylhydroxylamineIn 2021 ,《Mechanism-based design of quinoline potassium acyltrifluoroborates (KATs) for rapid amide-forming ligations at physiological pH》 appeared in Journal of the American Chemical Society. The author of the article were Tanriver, Matthias; Dzeng, Yi-Chung; Da Ros, Sara; Lam, Erwin; Bode, Jeffrey W.. The article conveys some information:

Potassium acyltrifluoroborates (KATs) undergo chemoselective amide-forming ligations with hydroxylamines. Under aqueous, acidic conditions these ligations can proceed rapidly, with rate constants of ~20 M-1 s-1. The requirement for lower pH to obtain the fastest rates, however, limits their use with certain biomols. and precludes in vivo applications. By mechanistic investigations into the KAT ligation, including kinetic studies, X-ray crystallog., and DFT calculations, we have identified a key role for a proton in accelerating the ligation. We applied this knowledge to the design and synthesis of 8-quinolyl acyltrifluoroborates, a new class of KATs that ligates with hydroxylamines at pH 7.4 with rate constants >4 M-1 s-1. We trace the enhanced rate at physiol. pH to unexpectedly high basicity of the 8-quinoline-KATs, which leads to their protonation even under neutral conditions. This proton assists the formation of the key tetrahedral intermediate and activates the leaving groups on the hydroxylamine toward a concerted 1,2-BF3 shift that leads to the amide product. We demonstrate that the fast ligations at pH 7.4 can be carried out with a protein substrate at micromolar concentrations The experimental part of the paper was very detailed, including the reaction process of N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3Recommanded Product: N-tert-Butoxycarbonylhydroxylamine)

Gillespie, James E.; Morrill, Charlotte; Phipps, Robert J. published an article in 2021. The article was titled 《Regioselective Radical Arene Amination for the Concise Synthesis of ortho-Phenylenediamines》, and you may find the article in Journal of the American Chemical Society.Application In Synthesis of N-tert-Butoxycarbonylhydroxylamine The information in the text is summarized as follows:

The formation of arene C-N bonds directly from C-H bonds is of great importance and there has been rapid recent development of methods for achieving this through radical mechanisms, often involving reactive N-centered radicals. A major challenge associated with these advances is that of regiocontrol, with mixtures of regioisomeric products obtained in most protocols, limiting broader utility. We have designed a system that utilizes attractive noncovalent interactions between an anionic substrate and an incoming radical cation in order to guide the latter to the arene ortho position. The anionic substrate takes the form of a sulfamate-protected aniline and telescoped cleavage of the sulfamate group after amination leads directly to ortho-phenylenediamines, key building blocks for a range of medicinally relevant diazoles. Our method can deliver both free amines and monoalkyl amines allowing access to unsym., selectively monoalkylated benzimidazoles and benzotriazoles. As well as providing concise access to valuable ortho-phenylenediamines, this work demonstrates the potential for utilizing noncovalent interactions to control positional selectivity in radical reactions.

COA of Formula: C5H11NO3In 2021 ,《Hydroxylamine-Derived Reagent as a Dual Oxidant and Amino Group Donor for the Iron-Catalyzed Preparation of Unprotected Sulfinamides from Thiols》 was published in Angewandte Chemie, International Edition. The article was written by Chatterjee, Sayanti; Makai, Szabolcs; Morandi, Bill. The article contains the following contents:

An iron catalyzed reaction for the selective transformation of thiols (-SH) to sulfinamides (-SONH2) by a direct transfer of -O and free -NH2 groups has been developed. The reaction operates under mild conditions using a bench stable hydroxylamine derived reagent, exhibits broad functional group tolerance, is scalable and proceeds without the use of any precious metal catalyst or addnl. oxidant. This novel, practical reaction leads to the formation of two distinct new bonds (S=O and S-N) in a single step to chemoselectively form valuable, unprotected sulfinamide products. Preliminary mechanistic studies implicate the role of the alc. solvent as an oxygen atom donor.

The article was titled 《Enantioselective α-Etherification of Branched Aldehydes via an Oxidative Umpolung Strategy》.HPLC of Formula: 36016-38-3 The article contains the following contents:

A survey of benzoquinone oxidants identified p-fluoranil and DDQ as suitable reaction partners. p-Fluoranil enables the preparation of α-aryloxylated aldehydes using phenol nucleophiles in up to 91% ee, following either a one-step or a two-step, one-pot protocol. DDQ allowed for a more general etherification protocol in combination with a broader range of alc. nucleophiles with enantioselectivities up to 95% ee. Control experiments and isolation of a key quinol intermediate supports a mechanism proceeding via an SN2 dynamic-kinetic resolution These studies provided the basis for an aminocatalytic umpolung concept that allows for the asym. construction of tertiary ethers in the α-position of aldehydes. In the experiment, the researchers used many compounds, for example, N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3HPLC of Formula: 36016-38-3)

Formula: C5H11NO3In 2019 ,《Traceless Templated Amide-Forming Ligations》 was published in Journal of the American Chemical Society. The article was written by Osuna Galvez, Alberto; Bode, Jeffrey W.. The article contains the following contents:

Template assistance allows organic reactions to occur under highly dilute conditions-where intermol. reactions often fail to proceed-by bringing reactants into close spatial proximity. This strategy has been elegantly applied to numerous systems, but always with the retention of at least one of the templating groups in the product. In this report, the authors describe a traceless, templated amide-forming ligation that proceeds at low micromolar concentration under aqueous conditions in the presence of biomols. The authors utilized the unique features of an acylboronate-hydroxylamine ligation, in which covalent bonds are broken in each of the reactants as the new amide bond is formed. By using streptavidin as a template and acylboronates and O-acylhydroxylamines bearing desthiobiotins that are cleaved upon amide formation, the authors demonstrate that traceless, templated ligation occurs rapidly even at submicromolar concentrations The requirement for a close spatial orientation of the functional groups-achieved upon binding to streptavidin-is critical for the observed enhancement in the rate and quantity of product formed.

And the article was published in Journal of the American Chemical Society in 2019. HPLC of Formula: 36016-38-3 The author mentioned the following in the article:

Feedstock aromatic compounds are compelling low-cost starting points from which mol. complexity can be generated rapidly via oxidative dearomatization. Oxidative dearomatizations commonly rely heavily on hypervalent iodine or heavy metals to provide the requisite thermodn. driving force for overcoming aromatic stabilization energy. This article describes oxidative dearomatizations of 2-(hydroxymethyl)phenols via their derived bis(dichloroacetates) using hydrogen peroxide as a mild oxidant that intercepts a transient quinone methide. A stereochem. study revealed that the reaction proceeds by a new mechanism relative to other phenol dearomatizations and is complementary to extant methods that rely on hypervalent iodine. Using a new chiral phase-transfer catalyst, the first asym. syntheses of 1-oxaspiro[2.5]octa-5,7-dien-4-ones were reported. The synthetic utility of the derived 1-oxaspiro[2.5]octadienones products is demonstrated in a downstream complexity-generating transformation.
