Synthesis of 3-[(coumarinyl)carbonyl]-3a,8b-dihyroindeno[1,2-b]pyrrole-4(1H)-ones and their conversion to coumarin bearing spiro[isobenzofuran-1,2′-pyrrole] moiety compounds via oxidative cleavage reaction

Abstract

The synthesis of substituted coumarin derivatives bearing indenopyrrole and spiro[isobenzofuran-1,2′-pyrrole] in a four-component sequential reaction and following oxidative cleavage reaction.
