Abstract

Amidated and deamidated chiral DAP-d-Ala analogues were prepared by olefin cross-metathesis of 12 with modified d-allylglycines using Grubbs’ 2nd generation catalyst. Hydrogenation and deprotection of these precursors provided four chiral (2S,6R)-DAP-d-alanine derivatives that were examined as substrates for Mtb l,d-transpeptidases in a 14C-d-Ala exchange reaction.
