Abstract
The 1-alken-3-ones (Ia) and the α,α-bis(ethylthio) ester (IIb) or the α,β-unsaturated esters (Ib) and the bissulfenyl ketone (IIa) undergo cyclocondensation to produce the bis(sulfenyl)cyclohexanediones (III) which are deprotected, forming the trihydroxybenzenes (IV).

The 1-alken-3-ones (Ia) and the α,α-bis(ethylthio) ester (IIb) or the α,β-unsaturated esters (Ib) and the bissulfenyl ketone (IIa) undergo cyclocondensation to produce the bis(sulfenyl)cyclohexanediones (III) which are deprotected, forming the trihydroxybenzenes (IV). Analogous reaction of the methylenelactone (V) with (IIa) gives the dibenzofuran derivative (VII).
