description

The crystal structure of the title compound, C8H8O3, was determined in the course of our studies of the synthesis of cyclo­penta­[1,2-b]furan-4-one derivatives. The title compound has two chiral C atoms and was obtained as a racemic mixture. It was found to possess a vinylogous acid group with an E configuration at the double bond. The compound exists in the hydroxy­methyl­ene and not in the tautomeric carbaldehyde form. The asymmetric unit consists of two molecules.
