2-Ethyl-5,10-dimethyl-, 13-ethyl-10-methyl-4,5-benzo-, 2-ethyl-10-methyl-4,5-benzo-, and 2-ethyl-4,5:10,11-dibenzo-6,8-bisdehydroannulenone were synthesized.Influence of α-ethyl substitution upon the skeleton of the bisdehydroannulenone ring system is discussed on the basis of 1H NMR and UV spectra of these annulenones and their corresponding α-methyl-substituted derivatives.
