摘要: An In(III)-catalyzed vinylogous addition of O-silyl vinylketene acetals to 2,3-dihydro-4-pyridinones has been developed. The method features the unprecedented employment supersilyl groups influence γ versus α regiochemical control Mukaiyama–Michael (vM−Michael) reactions when γ-substituted are used. We also demonstrate that these allow facile access quinolizidine-based alkaloids such as deoxynupharidine and well lasubine I II.
