  Synthesis of Optically Active Constrained 2-Substituted Norstatines:  A Straightforward Application of Seebach's “SRS” Synthetic Principle

  摘要：

  A straightforward two-step methodology of synthesis of optically active (2,R)-substituted norstatines via addition of N-tert-butoxycarbonyl-substituted aldimines to (2S)-chiral enolates of 1,3-dioxolan-4-ones has been developed. In particular, the use of the natural (2S)-malic acid is examined for the synthesis of potential GABAergic spirocyclic gamma-lactams.

  1,3-Dioxolanone alcohols, prepared via the addition of chiral lithium enolates of 1,3-dioxolan-4-ones to aldehydes, are suitable intermediates for the synthesis of chiral trisubstituted isoserines or trisubstituted 3-hydroxy-β-lactams. In particular, the methyl ester of 2-methyl-3-(2-furyl)isoserinic acid and two 3-methyl-3-hydroxy-β-lactams bearing either a 2-furyl or a phenyl substituent at C-(4)

  New and efficient synthetic routes to 2-alkylisoserines, their dipeptides and 2′-alkyl-taxoids were synthesized from enantiopure 3-alkyl-β-lactams 3 which were obtained through extremely distereoselective alkylation of β-lactams 2.
