摘要:
For the first time, enzymatic resolution of alpha-azido acid amides has been successfully demonstrated with high yields and enantiomeric excess. In one case dynamic kinetic resolution was achieved leading to more than 50% yield of the enantiomerically pure azido acid. Chiral HPLC was also used to separate racemic alpha-azido acids and the separation process was automated. Two routes to enantiopure alpha-azido acid building blocks for solid-phase peptide synthesis have, therefore, been established. (C) 2000 Elsevier Science Ltd. All rights reserved.
