摘要
The first enantioselective vinylogous aldol-cyclization cascade reaction of allyl pyrazoleamides with isatins is reported. With 1 mol% of Takemoto catalyst, optically active spirocyclic oxindole-dihydropyranones were obtained in excellent yields (93-99%) and good-to-excellent enantioselectivities (82-97% ee).
