Iodine-mediated direct synthesis of multifunctional 2-aminobenzimidazoles from N-substituted o-diaminoarenes and isothiocyanates was written by Wang, Zhen;Zhao, Qiongli;Hou, Jiao;Yu, Wenquan;Chang, Junbiao. And the article was included in Tetrahedron in 2018.Application of 2253-73-8 The following contents are mentioned in the article:

Multifunctional 2-aminobenzimidazoles were directly synthesized through sequential addition of N-substituted o-diaminoarenes to isothiocyanates, formation of carbodiimides via I₂-mediated oxidative desulfurization, and intramol. cycloaddition This efficient and eco-friendly synthetic process provides a facile access to diverse 2-aminobenzimidazole derivatives from readily accessible substrates under mild reaction conditions in a scalable fashion. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Application of 2253-73-8).

Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application of 2253-73-8

A one-pot assembly of fully substituted alkyl 5-aminothiophene-2-carboxylates from allenes, isothiocyanates, and alkyl 2-bromoacetates was written by Nedolya, Nina A.;Tarasova, Ol’ga A.;Albanov, Alexander I.;Trofimov, Boris A.. And the article was included in Journal of Organic Chemistry in 2017.Recommanded Product: Isopropylisothiocyanate The following contents are mentioned in the article:

A simple approach to highly functionalized multisubstituted thiophenes such as alkyl 4-alkoxy-5-amino-3-methylthiophene-2-carboxylates, e.g., I, through the one-pot sequential reaction of α-lithiated alkoxyallenes with isothiocyanates and alkyl 2-bromoacetates has been discovered. The process proceeds quickly via in situ formation and intramol. cyclization of alkyl 2-[(2-alkoxybuta-2,3-dienimidoyl)sulfanyl]acetates (1-aza-1,3,4-trienes). This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Recommanded Product: Isopropylisothiocyanate).

Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Recommanded Product: Isopropylisothiocyanate

Expeditious Scalable Catalyst-Free One-Pot Synthesis of 4-Alkoxy-5-amino-3-methylthiophene-2-carbonitriles via Sequential Reactions of Lithiated Alkoxyallenes with Isothiocyanates and 2-Bromoacetonitrile was written by Nedolya, Nina A.;Tarasova, Olga A.;Albanov, Alexander I.;Trofimov, Boris A.. And the article was included in Synthesis in 2018.Related Products of 2253-73-8 The following contents are mentioned in the article:

A synthetically simple and convenient approach to tetrasubstituted thiophenes with rare combination of the alkoxy, amino and cyano groups was developed. The assembly of polyfunctionalized thiophene ring was implemented in one preparative step by sequential addition of isothiocyanate and 2-bromoacetonitrile to the lithiated (with n-BuLi) alkoxyallene. The reaction proceeded through in-situ formation and intramol. cyclization of cyanomethyl 2-alkoxy-N-buta-2,3-dienimidothioate (1-aza-1,3,4-triene). This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Related Products of 2253-73-8).

Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Related Products of 2253-73-8

And the article was included in Journal of Organic Chemistry in 2020.Name: Octyl acetate The following contents are mentioned in the article:

Sn-catalyzed mild protocol was reported for ring expansion of peroxyoxindoles to afford a series of substituted 2H-benzo[b][1,4]oxazin-3(4H)-one derivatives In this protocol, authors showed the in-situ conversion of tert-Bu peroxy compounds into peresters with the aid of external esters, which then underwent the ring-expansion process and the incipient carbocation was trapped with the alc. residue generated from the esters. The reaction was also demonstrated in a continuous flow process. This study involved multiple reactions and reactants, such as Octyl acetate (cas: 112-14-1Name: Octyl acetate).

Octyl acetate (cas: 112-14-1) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Name: Octyl acetate

Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Synthetic Route of C4H7NS
