摘要： 在碱性条件下,α,α-二乙酰基二硫缩烯酮和芳醛的缩合反应受烷硫基的影响.α,α-二乙酰基二苄硫缩烯酮1和芳醛3缩合生成单面缩合脱乙酰基产物α-肉桂酰基二苄硫缩烯酮4;α,α-二乙酰基环二硫缩烯酮2和芳醛3缩合生成双面缩合产物α,α-二肉桂酰基环二硫缩烯酮5.

Abstract: The condensation reactions of α,α-diacetyl ketene dithioacetals with arylaldehydes catalyzed by sodium tert-butoxide were performed. These reactions were affected by the alkylthio groups. The deacylation-condensation products α-cinnamoyl ketene dibenzylthioacetals 4 were obtained by the reaction of α,α-diacetyl ketene dibenzylthioacetals 1 with arylaldehydes 3. α,α-Dicinnamoyl ketene cyclic dioacetals 5 was formed when the reaction was performed between α,α-diacetyl ketene cyclic dioacetals 4 and arylaldehydes 3.

Key words: α,α-Diacetyl ketene dithioacetals, Arylaldehydes, Condensation
