Abstract

A new simple and efficient way to 2-CF₃-imidazo[1,2-a]pyridines and 2-CF₃-imidazo[1,2-a]quinolines by the reaction of 1,1,1-trifluoro-4-(phenylsulfonyl)but-3-ene-2,2-diols 1a,b with various 2-aminopyridines is described. The cyclization reaction proceeds diastereospecifically under mild conditions in water.

Key words

diastereoselectivity - cycloaddition - heterocycles - imidazo[1,2-a]pyridines - imidazo[1,2-a]quinolines - sulfones
