afford the corresponding cycloadducts (2), from which thiophenol is eliminated by the treatment with sodium alkoxide to give the corresponding 2H-thiopyran derivatives (3). The cycloadducts 2 with styrene and indene do not undergo elimination. The reactions of thioketone 1 with cycloalkenones give both the cycloadducts and the elimination products, even in the absence of a base. The reactions of 1 with
2-[(苯硫基)亚甲基]四氢萘-1-硫酮 (1) 与丙烯酸甲酯、甲基乙烯基酮、丙烯腈和其他缺电子双烯体的杂狄尔斯-阿尔德反应得到相应的环加合物 (2),苯硫酚由此用醇钠处理消除,得到相应的 2H-噻喃衍生物 (3)。带有苯乙烯和茚的环加合物 2 不发生消除。即使在没有碱的情况下,硫酮 1 与环烯酮的反应也会产生环加合物和消除产物。1 与丙烯酰、巴豆酰、肉桂酰和 3-甲基-2-丁烯酰氯反应生成二烯碳硫代 S-酯,收率良好,通过劳森试剂处理将其转化为稳定的二烯碳二硫代酯。在 1 与 2-溴丙烯酸甲酯的反应中,
