Robinsonannelation of the 10-hydroxymethylene derivative of 1β,4,4-trimethyl-3α,5α-tricyclo[5.4.0.03,5]undec-7-en-9-one with methyl and ethyl vinyl ketones has yielded hydrocyclopropa[b]anthracenones whose products of reduction and cyclopropane scission are reported. The stereochemistry of the tetracycles and tricycles are analysed by the 13C n.m.r. spectral and c.d. methods.
