(5S,6R)-6-Bromo-6-methyl-5-phenyl-3,4,5,6-tetrahydro-2H-cyclopenta[b]pyran-7-one
The title compound, C15H15BrO2, was synthesized by a Brønsted acid-catalysed domino electrocyclization-halogenation reaction. The five-membered ring is essentially planar (r.m.s. deviation 0.006 Å) and forms a dihedral angle of 72.7 (3)° with the attached phenyl ring. The six-membered heterocycle adopts a half-chair conformation. The crystal packing is stabilized by a C—H[cdots, three dots, centered]O contact.
