The synthesis of a series of novel tricyclic p-quinone methides (p-QMs) from 5-(p-alkyloxyaryl)-10,11-dihydrodibenzo[a,d]cyclohepten-5-ol and related substrates in moderate-to-good yields is reported. The reaction is proposed to proceed under mild acidic conditions by O-dealkylation of the p-alkoxy group on the p-position of the pendant 5-aryl ring on the B-ring of the tricyclic system.The effect of
