Methyl 8-oxo-2-phenyl-1-oxaspiro[4.5]deca-2,6,9-triene-3-carboxylate

Abstract

The title compound, C17H14O4, is a 5/6 spiro-ring fused system, where the five- and six-membered rings are inclined to one another by 89.79 (5)° at the spiro-carbon. In the crystal, non-classical C—H ... O hydrogen bonds form inversion dimers and connect the molecules into chains along [001].
