Three-Component Synthesis of Alkyl-Substituted Functionalized 4H-Thiopyrans, 1,2- and 1,4-Dihydropyridines, 2-Alkylsulfanylpyridines, Thieno[2,3-b]pyridines, and Cyclohexa-1,3-diene.

Abstract

Three-component condensation of aliphatic aldehydes with CH-acids has afforded functionalized alkylsubstituted 4H-thiopyrans, 1,2- and 1,4-dihydropyridines, 2-alkylsulfanylpyridines, thieno[2,3-b]pyridines, and cyclohexa-1,3-diene.
