A mild method for the diastereoselective formation of C4, C5-disubstituted cyclopentenones has been developed, involving formation of a pentadienyl cation via diastereoselective oxidation of a vinyl alkoxyallene. Conrotatory electrocyclization provides the cyclopentenone product. The broad scope, mild conditions, and uncommon substitution pattern accessible through this transformation make it a useful
已经开发了一种非对映选择性形成 C 4、C 5 -二取代环戊烯酮的温和方法,包括通过乙烯基烷氧基丙二烯的非对映选择性氧化形成戊二烯基阳离子。旋转电环化提供环戊烯酮产物。通过这种转化,广泛的范围、温和的条件和不常见的取代模式使其成为现有环戊烯酮合成方法的有用补充。
