Reformatsky Reaction of Methyl 1-Bromocyclopentane-1-carboxylate with 1-Aryl-3-(2-hydroxyphenyl)prop-2-en-1-ones

Abstract

Reformatsky reaction of methyl 1-bromocyclopentanecarboxylate with 1-aryl-3-(2-hydroxyphenyl)-prop-2-en-1-ones afforded 6-substituted 4-(2-aryl-2-oxoethyl)-2H,4H-spiro[chromene-3,1′-cyclopentan]-2-ones. A probable reaction mechanism was proposed on the basis of DFT/TZVP quantum chemical calculations.
