Abstract

Coumarin Substituted Pyrrolo-Fused Heterocyclic Systems by 1,3-Dipolar Cycloadditon Reactions. -The title heterocyclic systems are obtained by 1,3-dipolar cycloaddition of in situ from several N-heterocycles and chromenone (II) generated cycloimmonium-ylides with electron-deficient alkynes. -(POPA*, M.
