And the article contained the following:

A novel, straightforward chem. platform to prepare polymers with covalently bound amine functional groups has been developed for applications as coatings that scavenge formaldehyde emissions. For the polymer preparation, an amine-thiol-ene conjugation process was used to combine N-(allyloxy)carbonyl homocysteine thiolactone monomer with different amines, which simultaneously released a thiol group for subsequent thiol-ene radical polymerization Results of the European standard formaldehyde release test by the flask method indicated that the obtained polymers with higher amine loadings resulted in a greater reduction in formaldehyde concentration Urea-formaldehyde adhesive was overcoated with scavenging polymers, which resulted in a significant reduction in formaldehyde emissions. The amine-functionalized polymers were characterized by NMR and DSC before and after exposure to formaldehyde. After exposure to formaldehyde, polymers exhibited addnl. proton peaks in the NMR spectra and their glass transition temperature increased, which implied that formaldehyde was bound to the polymers. The experimental process involved the reaction of 3-Aminodihydrothiophen-2(3H)-one hydrochloride(cas: 6038-19-3).Product Details of 6038-19-3

This work focused on surface modification of magnetite nanoparticle (MNP) with poly(poly(ethylene glycol) monomethyl ether methacylate)-b-(poly(N-isopropylacrylamide)-st-poly(thiolactone acrylamide)), PPEGMA-b-(PNIPAAm-st-PTlaAm), diblock copolymer, synthesized via reversible addition-fragmentation chain transfer (RAFT) polymerization to obtain the particles having good water dispersible PPEGMA brushes, thermo-responsive PNIPAAm, and reactive thiolactone groups of PTlaAm. The thiolactone moiety in the copolymer can readily react with amino groups grafted on MNP surface and essentially induced the formation of MNP nanocluster. According to transmission electron microscopy (TEM), the size of the nanocluster ranged between 200 and 500 nm per cluster with 8 to 10 nm in diameter for each particle. Hydrodynamic diameter of the nanocluster significantly decreased as the dispersion temperature increased from 25° C to 45° C due to the shrinkage of thermo-responsive PNIPAAm when crossing its lower critical solution temperature (LCST). This stable nanocluster might be potentially used as a magnetic carrier for control release of entrapped entities with a thermally triggering mechanism. The experimental process involved the reaction of 3-Aminodihydrothiophen-2(3H)-one hydrochloride(cas: 6038-19-3).SDS of cas: 6038-19-3

On November 2, 2016, Martens, Steven; Van den Begin, Jos; Madder, Annemieke; Du Prez, Filip E.; Espeel, Pieter published an article.Category: esters-buliding-blocks The title of the article was Automated Synthesis of Monodisperse Oligomers, Featuring Sequence Control and Tailored Functionalization. And the article contained the following:

Long, multifunctional sequence-defined oligomers were obtained on solid support from a protecting-group-free two-step iterative protocol, based on the inherent reactivity of a readily available mol. containing an isocyanate and a thiolactone. Aminolysis of the latter entity with an amino alc. liberates a thiol that reacts with an acrylate or acrylamide, present in the same medium. Subsequently, a new thiolactone can be reinstated by means of an α-isocyanato-γ-thiolactone. Different acrylic compounds were used to incorporate diverse functionalities in the oligomers, which were built up to the level of decamers. The reaction conditions were closely monitored in order to fine-tune the applied strategy as well as facilitate the translation to an automated protocol. The experimental process involved the reaction of 3-Aminodihydrothiophen-2(3H)-one hydrochloride(cas: 6038-19-3).Category: esters-buliding-blocks

A strategy for the synthesis of sequence-defined oligomers using a selective side-group insertion approach making use of thiophenol-catalyzed amidation reactions is herein reported. In this context, a new thiolactone-based, multistep, iterative protocol is designed, utilizing thioacrylates in combination with solid-phase synthesis for step-by-step growth, resulting in sequence-defined oligomers. Sequence definition and structure variation are introduced by substituting the thioacrylate side groups with a wide variety of amines.

Mommer, Stefan; Keul, Helmut; Moeller, Martin published an article in 2014, the title of the article was Tailored Thiol-Functional Polyamides: Synthesis and Functionalization.Electric Literature of 6038-19-3 And the article contains the following content:

In this article, a synthetic concept for the preparation of polyamides with functional side groups is described. First, the synthesis of a bis(thiolactone) monomer is shown in a concise three-step route from itaconic acid and DL-homocysteine thiolactone. The reactivity of the resulting bis(thiolactone) toward hexyl amine is examined Next, the bis(thiolactone) is reacted as A,A-type monomer with different B,B-type comonomers (1,12-diaminododecane and 1,3-bis(aminopropyl)tetramethyldisiloxane). Ring opening of the thiolactones by the diamines leads to polyamides with pendant thiol groups. Using two diamines in different ratios, the properties of the resulting polyamides are tuned (thermal properties are determined) and different mol. weights are acquired. Subsequently, the thiol groups are reacted with Me acrylate via Michael addition to functionalize the polyamides. Functionalization of thiol-functional polyamides using poly(ethylene glycol) monomethyl ether (mPEG) acrylates (Mn = 480 and 1700 g mol-1) results in water-soluble amphiphilic poly-amides with mol. weights higher than 10 000 g mol-1.

And the article contained the following:

Protein imprinted materials receive considerable attention in biol. scope but restricted about practical use for the lack of adsorption efficiency and rebinding specificity. To approach the dearth, imprinted polymers or ligands capable of designable structure, herein, the facile thiolactone-based conjugates accompanied by multiple functional units, were put forward into imprinting system as protein anchors by click chem. Due to the simple implementation and flexible reconstitution of this conjugation strategy, a series of thiol-ene-amine segments were fabricated to capture bovine serum albumin (BSA) for generating imprinting cavities through dopamine self-polymerization on well-defined hollow magnetic substrates. Among them, the BSA-imprinted microspheres based on thiol-ene-MA conjugates (MA referred as 3-morpholinopropylamine) not only exhibited remarkable rebinding ability (adsorption capacity: 209.22 mg/g, imprinting factor: 4.59) and efficient saturation adsorption (30 min), but also presented satisfactory selectivity in the individual and competitive protein samples. Assisted with thiol-ene-amine conjugation, the elaborate magnetic imprinted materials for specific separating target macromols. hold great promising in applications.

Fluorescent poly(amide-imide)s are promising materials for use in photonics due to their controllable optical properties and excellent flexibility. Although unconventional fluorescent polymers were flourishing recently, the fluorescence of aliphatic poly(amide-imide)s has never been realized until now. Their poor solubility and intolerance to reactive groups during synthesis prohibit access for the modification of poly(amide-imide)s. Here, the authors synthesize a functional thiolactone-maleimide monomer via Cu(II)-catalyzed azide alkyne cycloaddition and employ a strategy combining aminolysis of thiolactones and amine-maleimide Michael addition for the synthesis of fluorescent aliphatic poly(amide-imide)s with 2-aminosuccinimide fluorophores. Also, in situ generated thiols enable the poly(amide-imide)s to undergo facile PEGylation via a thiol-methacrylate Michael addition reaction to accomplish excellent solubility in organic solvents and in H2O.

AB’ type monomers containing a thiolactone unit and vinyl ether moiety have been prepared with high yields. Aminolysis of the thiolactone moiety generates the corresponding thiol in situ, and upon UV-irradiation, radical polyaddition occurs in the same medium, yielding linear poly(amide-urethane)s with different side chain residues and (Poly(Ethylene Oxide)) PEO-like backbone. Moreover, these unique polymers feature lower critical solution temperature behavior in water. Systematic modification of the responsive polymers reveals the influence of the variation of the side chains and the backbone structure on the corresponding solubility properties. In selected cases, multiresponsive polymers have been developed, which also respond to pH and metal concentration The experimental process involved the reaction of 3-Aminodihydrothiophen-2(3H)-one hydrochloride(cas: 6038-19-3).Quality Control of 3-Aminodihydrothiophen-2(3H)-one hydrochloride
