The efficient synthesis of (3R,5R)-5-hydroxypiperazic acid and its diastereomer using Lewis acid-promoted diastereoselective Strecker synthesis
摘要:
The stereoselective synthesis of (3R,5R)-5-hydroxypiperazic acid, a component of naturally occurring antibiotic cyclodepsipeptides, and its diastereomer was achieved via the use of Lewis acid-promoted diastereoselective Strecker synthesis as a key step, in which an interesting stereochemical reversal of diastereoselectivity by the choice of Lewis acid catalyst was observed.

Employing Hamada's chemistry with MAOS optimization of several steps, an expedient route to key (3S,5S)- and (3R,5R)-gamma-hydroxy and (3R,5S)-gamma-chloropiperazic acids, was developed en route to a total synthesis of piperazimycin A. (C) 2008 Elsevier Ltd. All rights reserved.
