A stereoselective synthesis of a hydroxyethylene dipeptide isostere for Phe-Gly,(4S, 5S)-4-hydroxy-5-amino-6-phenylhexanoic acid, is described. The use of dibenzyl protecting groups on ketoamine 5 accounts for the selectivity on reduction. Also, the dibenzyl group plays a role in directing the introduction of a third chiral center.
描述了对Phe-Gly,(4S,5S)-4-羟基-5-氨基-6-苯基己酸的羟乙烯二肽等排异构体的立体选择性合成。在酮胺5上使用二苄基保护基说明了还原的选择性。同样,二苄基在引导第三个手性中心的引入中也起作用。
