  Stereoselective Alkylation of N-Boc-protected-5-substituted δ-Lactams:  Synthesis of α,δ-Disubstituted δ-Amino Acids

  摘要：

  [GRAPHICS]N-Boc-protected-5-substituted delta-lactams were readily prepared from the corresponding beta(3)-amino acids. Alkylation reactions of their Na enolates with various electrophiles proceeded in high yields with high facial selectivity. The structure of the alkylation products was confirmed by Single-crystal X-ray analysis. This method provides a fast access to optically active alpha,delta-disubstituted delta-amino acids.
