Abstract: The new multicomponent reaction (MCR) has been found: one-pot selective and efficient formation of the new 5-(4-hydroxy-2-oxo-1,2-dihydropyridin-3-yl)-substituted 5H-chromeno[2,3-b]pyridines in 61–97% yields directly from simple and easily available salicylaldehydes, malononitrile dimer and 4-hydroxypyridine-2(1H)-ones in small amount… read more here.
