  Asymmetric Synthesis of anti-α-Substituted β-Amino Ketones from Sulfinimines

  摘要：

  Previously unknown, enantiopure, beta-amino ketones were prepared in modest yield by addition of lithium reagents to N-sulfinyl anti-alpha-substituted beta-amino Weinreb amides. Grignard reagents failed to add to these Weinreb amides in contrast to the syn-alpha-substituted isomers which did. The anti-alpha-substituted beta-amino Weinreb amides were prepared by addition of LiN(OMe)Me to the corresponding N-sulfinyl anti-alpha-substituted beta-amino esters because alpha-alkylation of N-sulfinyl beta-amino Weinreb amide enolates resulted in poor diastereoselectivities.
