The reaction of tin(II) enolates with various α ,β-unsaturated carbonyl compounds is examined. When TMSCl is added as an activator of the α,β-unsaturated ketones, the Michael addition reaction proceeds smoothly to give the corresponding 1,4-adduct in good yield. When 1,4-benzoquinone and its mono-imino derivative are employed as acceptors in conjunction with dichloromethylsilane- DMAP activator, a
研究了锡(II)烯醇化物与各种α,β-不饱和羰基化合物的反应。当加入TMSCl作为α,β-不饱和酮的活化剂时,迈克尔加成反应顺利进行,以良好的产率得到相应的1,4-加合物。当将1,4-苯醌及其单亚氨基衍生物与二氯甲基硅烷-DMAP活化剂一起用作受体时,发生新的加成-还原反应以提供α-芳基羰基化合物。
