(S)-6-{[(S)-2,2-Dimethyl-1,3-dioxolan-4-yl]meth-yl}-5,5-difluoro-5,6-dihydro-2H-pyran-2-one.

ABSTRACT: The title compound, C(11)H(14)F(2)O(4), is a ?,?-gem-difluorinated ?,?-unsaturated ?-lactone. The dioxolane five-membered ring and the lactone ring adopt half-chair conformations. There are two inter-molecular C-H?O inter-actions involving the carbonyl group as an acceptor which stabilize the crystal structure.
