(S)-tert-Butyl (1-(methoxy(methyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate (cas: 87694-53-9) 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. 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.Quality Control of (S)-tert-Butyl (1-(methoxy(methyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate

Structurally Diverse Acyl Bicyclobutanes: Valuable Strained Electrophiles was written by Schwartz, Brett D.;Zhang, Meng Yao;Attard, Riley H.;Gardiner, Michael G.;Malins, Lara R.. And the article was included in Chemistry – A European Journal in 2020.Quality Control of (S)-tert-Butyl (1-(methoxy(methyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate This article mentions the following:

This work reported two efficient pathways for the rapid preparation of over 20 structurally diverse bicyclo[1.1.0]butane (BCB) ketones, such as I [R = cuban-1-yl, BOCHNCH2, 4-MeOC6H4, etc.] encompassing simple alkyl and aryl derivatives, as well as unprecedented amino acid, dipeptide, bioisostere, and bifunctional linchpin reagents currently inaccessible using literature methods. Analogs were readily forged in two steps and in high yields from simple carboxylic acids or through unsym. ketone synthesis beginning with a convenient carbonyl dication equivalent The utility of this novel toolbox of strained electrophiles for selective modification of proteinogenic nucleophiles was highlighted. In the experiment, the researchers used many compounds, for example, (S)-tert-Butyl (1-(methoxy(methyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate (cas: 87694-53-9Quality Control of (S)-tert-Butyl (1-(methoxy(methyl)amino)-1-oxo-3-phenylpropan-2-yl)carbamate).
