We have described the simple, convenient and high yielding one-potsynthesis of a library of highlyfunctionalized hexa-substituted 1,4-dihydropyridines (1,4-DHPs) by 2-aminopyridine catalysed pseudo three-component reaction of nitroketene-N,S-acetals and aldehydes. This domino transformation involves formation of dihydropyridine ring by creation of two C–C bonds and one C–N bond, all of them taking
