An efficient synthesis of optically active α-(t-butoxycarbonylamino)-aldehydes from α-amino acids was written by Fehrentz, Jean Alain;Castro, Bertrand. And the article was included in Synthesis in 1983.Application of 87694-53-9 This article mentions the following:
BocNHCHRCON(OMe)Me (I; Boc = Me3CO2C; R = Me, CH2CHMe2, CHMeEt, CHMe2, CH2Ph, CHMeOCH2Ph) were reduced by LiAlH4 to give BocNHCHRCH(OLi)N(OMe)Me, which were hydrolyzed in situ to give title aldehydes BocNHCHRCHO. I were prepared by condensing BocNHCHRCO2H with HN(OMe)Me.HCl by BOP in CH2Cl2 containing Et3N. 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: 87694-53-9Application of 87694-53-9).
(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. 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.Application of 87694-53-9
