GRAPHICAL ABSTRACT ABSTRACT The [3+2] cycloaddition reaction of mesityl propargyl sulfide with ethyl glyoxylate was found to occur by using tin(IV) chloride to give a 2,5-dihydrofuran derivative. On the other hand, when 3-silyl propargyl sulfides were used, allyl alcohols were obtained. In the case of propargyl sulfides possessing dimethyl groups at the α-position of the propargyl group, cycloaddition
图形摘要摘要发现通过使用氯化锡 (IV) 可发生甲基炔丙基硫醚与乙醛酸乙酯的 [3+2] 环加成反应,生成 2,5-二氢呋喃衍生物。另一方面,当使用 3-甲硅烷基炔丙基硫化物时,得到烯丙醇。在炔丙基的α-位具有二甲基的炔丙基硫化物的情况下,即使炔丙基上存在甲硅烷基,也获得环加成产物。此外,甲基炔丙基硒化物还通过氯化锡(IV)与乙醛酸乙酯反应,得到相应的[3+2]环加成产物。
