Abstract: The addition of β,β-1,3-propylenedithio-α,β-unsaturated ketones 1 with methallyl Grignard reagent yielded carhinols 2.Catalyzed by mercuric chloride,carbinols 2 wereconverted to hydroxyethyl arylthio ethers 3 in the solvent of mercaptoethanol.When cat-alyzed by sulfuric acid, carbinols 2 were converted to α,β-unsaturated cyclohexanones 4.This conversion provides a new methd to the synthetesis of compound 4 and its analogues.

Key words: α-Oxo ketene cyclic dithioacetals, Mercaptoethanol, Substitution-cycloaromatization, Hydroxyethyl arylthio ether, Synthesis
