strategy has been used for the concise and efficient enantioselective formal synthesis of Annonaceous acetogenin cis-solamin. Our synthetic strategy comprises concise preparation of the diepoxyester via an 11-membered silaketal constructed by ring-closing metathesis after the dimerization of chiral epoxides, and uses an acid-catalyzed tandem intramolecular SN2-like reaction to construct the threo-cis-threo
已经采用了一种不同的策略来简便,高效地合成Annanoaceous acetogenin顺式-solamin的对映选择性形式。我们的合成策略包括通过手性环氧化物二聚后通过闭环易位而构建的11元硅酮来制备二环氧酯,并使用酸催化的串联分子内S N 2类反应来构建苏式-顺式-苏式四氢呋喃-二醇部分的构型。
