A sequential intramolecular-intermolecular enantioselective alkene difunctionalization reaction has been developed which is thought to proceed through Pd-catalyzed quinone methide formation. The synthesis of new chiral heterocyclic compounds with adjacent chiral centers is achieved in enantiomeric ratios up to 99:1 and diastereomeric ratios up to 10:1.
已经开发了连续的分子内-分子间对映选择性烯烃双官能化反应,该反应被认为是通过 Pd 催化的醌甲基化物形成进行的。具有相邻手性中心的新型手性杂环化合物的合成以高达 99:1 的对映体比例和高达 10:1 的非对映体比例实现。
