Abstract
In the title compound, alternatively called α-hydroxy-γ-alkylidenebutenolide, C12H16O3, two independent molecules (AandB) crystallize in the asymmetric unit in each of which the 5,6-dihydrobenzo ring has an envelope conformation. The torsion angle along the butadiene chain in the γ-alkylidenebutenolide core is −177.9 (2)° for moleculeAand 179.9 (2)° for moleculeB. In the crystal, O—H...O hydrogen bonds between hydroxyl and carbonyl groups of adjacent independent molecules form dimers withR22(10) loops.
