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.

N-vinylpyrroles with 3,4-dihydroisoquinoline-N-oxides: formal (3 + 3)-cycloaddition proceeds instead of (3 + 2)-cycloaddition. In the case of benzoyl(3,4-dihydroisoquinolin-2-ium-2-yl)amides, reaction path does not change in the same conditions, but changing of the diastereoselectivity occurs and other diastereomer of (3 + 2)-cycloaddition became predominant.
