  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.
