Aziridine 2-carboxylate ester mediated asymmetric synthesis of α-alkyl β-amino acids
摘要:
The highly stereoselective ring opening of N-tosylaziridine 2-carboxylate esters with LiAlH4 followed by oxidation of the ensuing syn alcohols results in a highly efficient 4 step asymmetric synthesis of alpha-methyl beta-amino acids from N-sulfinylaziridine 2-carboxylate esters.

Syn-alpha-substituted beta-amino Weinrebamides are new chiral building blocks for asymmetricsynthesis of syn-alpha-substituted beta-amino acids, aldehydes, and ketones and are prepared by addition of prochiral lithium enolates of Weinrebamides to sulfinimines (N-sulfinyl imines).
