Abstract

1-Vinylpyrroles readily add to benzoylacetylene on grinding the reagents with silica gel at room temperature to form 2-(E)-(2-benzoylvinyl)-1-vinylpyrroles in 50-84% yield in a regio- and stereoselective manner.

Key words

1-vinylpyrroles - benzoylacetylene - silica gel - 2-(E)-(2-benzoylvinyl)-1-vinylpyrroles - 1,2-divinylpyrroles
