6,7-Dimethyl-3a,8a-dihydro-3H-8-oxacyclopenta[a]inden-5-yl benzoate

M. Czugler and P. Bombicz

Abstract: The title compound, C20H18O3, was prepared in a one-step synthesis by intramolecular cyclization following the sigmatropic rearrangement of the allyl aryl ether intermediate. The room-temperature crystal structure determination reveals a cis conformation of the ring annellation.
