Abstract

Several kinds of fused cyclic compounds were obtained by tandem Michael-Claisen condensation of ethyl 2-[bis (ethylthio) methyl] benzoate and ethyl 2-[1, 3] dithiolan-2-yl- benzoate with α, β-unsaturated carbonyl compounds. Treatment of the annulated products with mercury (II) perchlorate trihydrate or N-chlorosuccinimide gave naphthoquinones, naphthalenes, and anthracenes.
