Palladium-catalyzed cross-coupling of internal alkenes with terminal alkenes to functionalized 1,3-butadienes using C-H bond activation: Efficient synthesis of bicyclic pyridones

chemical equation presented A highly regioselective direct cross-coupling of internal alkenes of a-oxoketene dithioacetals with terminal alkenes has been successfully realized by palladiumcatalyzed C-H bond activation, affording functionalized 1,3-butadie

SYNTHESIS OF IMIDAZOPYRIDINE AND PYRIDOPYRIMIDINE DERIVATIVES BY THE ADDITION AND CYCLOCONDENSATION REACTIONS OF KETENAMINALS CONTAINING IMIDAZOLIDINE OR HEXAHYDROPYRIMIDINE RING WITH ESTERS OF α,β-UNSATURATED ACIDS

Ketenaminals 1 react with methyl propiolate, methyl acrylate and dimethyl acetylenedicarboxylate to afford the fused imidazopyridines and pyridopyrimidines 3,4 and 5, respectively.In some cases, the intermediate addition products 2 and 6b ar
