o-Thioquinone methide reacted with enamines to give [4+2] cycloadduct in good yield. In the case of morpholinoenamine, 1 : 2 adduct was obtained. Thiobenzoylketene thioacetals underwent dimerization accompanied by concomitant desulfurization upon reaction with 1-(1-pyrrolidinyl)cyclohexene. The reaction mechanism of these reactions were discussed. Some other reactions of thioacylketene thioacetals with enamines were also described.
