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 .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.
