摘要：
An elegant P(nBu)(3)-triggered synthetic approach has been developed towards multisubstituted 5,6-dihydropyridin-2(1H)-one and pyridin-2(1H)-one derivatives exploiting a domino process involving retro-Claisen/intra-MBH/Wittig/vinylogous aldol transformations as well as retro-Claisen/intra-MBH/ylide hydrolysis/oxidation sequences. This transformation demonstrates chemo- and regioselectivity as well as accessible high diversity enchancement in 17-90% isolated yield.
