An Environmentally Friendly Synthetic Method of 1,2-Dihydroisoquinoline Frameworks via Three-Component Reaction with o-Alkynylbenzaldehydes, Primary Amines, and Pronucleophiles
摘要:
Three-component reactions with ortho-alkynylbenzaldehydes, primary amines, and pronucleophiles (Nu-H), such as CHCl3, proceeded to give 1,2-dihydroisoquinoline derivatives in good to high yields in the absence of any catalysts under mild reaction conditions.
