Prochiral dilactone 1 has been synthesized and subjected to diastereo-selective nucleophilic opening. The structural features of chiral, enantiomerically pure nucleophiles have been optimized regarding their capability to perform prochiral recognition at dilactone 1. 3-Ketoglutaric mono acid products 2 of dilactone opening, which are versatile building blocks for natural product synthesis, have been
前手性双内酯1已合成,并经过非对映选择性亲核开放。关于手性,对映体纯的亲核试剂的结构特征,已对其在双内酯1上进行前手性识别的能力进行了优化。二内酯开口的3-酮戊二酸单酸产物2,是天然产物合成的通用组成部分,已经以高达84:16的非对映体比例获得,并通过随后的结晶至97.5:2.5而富集。
