An enantioselective preparation of vinylcyclopentanes has been achieved through the title reaction (see scheme). A range of aryl, heterocyclic, alkenyl, and alkyl substituted azlactone alkylidenes have been utilized, giving the cyclopentane products in good yield, diastereomeric ratio, and enantioselectivity.
通过标题反应实现了乙烯基环戊烷的对映选择性制备(参见方案)。已经使用了一系列芳基、杂环、烯基和烷基取代的吖内酯亚烷基,以良好的产率、非对映体比例和对映选择性得到环戊烷产物。
