  An efficient synthetic approach towards trans-β2,3-amino acids and demonstration of their utility in the design of therapeutically important β2,3-peptides and α,β2,3-peptide aldehydes

  摘要：

  An efficient synthetic approach towards trans-beta(2,3)-amino acids involving anti-selective aldol, azidation and controlled hydrolysis as key steps is discussed. Apart from structural elaboration of these building blocks to homo- and hetero-dipeptides, possibility of selective endocyclic cleavage of the chiral auxiliary was advantageously used in the preparation of of alpha,beta-hybrid peptide alcohols and corresponding aldehydes, which are promising candidates for biological evaluation against proteases of therapeutic interest.
