Assemble and build: The strategy depicted above merges different organocatalyzed conjugate addition reactions with the Seyferth–Gilmann homologation by which diverse optically active propargylic, homopropargylic and allenic products can be assembled in high yields and enantioselectivities.
组装和构建:上述策略将不同的有机催化共轭加成反应与Seyferth-Gilmann同系物合并,从而可以高收率和对映选择性组装各种光学活性的炔丙基,均炔丙基和烯丙基产物。
