Abstract: Трехкомпонентной конденсацией генерируемых in situ ацилметилидов пиридиния с ароматическими альдегидами и 4-гидрокси-6-метилпиридонами получена серия 3-арил-2-ацил-3,5-дигидрофуро[3,2- c ]пиридин-4(2 H )-онов. Реакция протекает диастереоселективно с образованием транс -изомеров и представляет собой каскадный процесс, включающий конденсацию Кнёвенагеля, карбо-реакцию… read more here.

Abstract: The three-component condensation of pyridinium acylmethylides generated in situ with aromatic aldehydes and 4-hydroxy-6-methylpyridones gave a series of 2-acyl-3-aryl-3,5-dihydrofuro[3,2-c]pyridin-4(2H)-ones. The reaction proceeds diastereoselectively with the formation of trans-isomers and represents a cascade process involving the… read more here.
