Triphenylphosphoranylideneacetamide (1) reacts with some Michael-acceptors to give crystalline 2-triphenylphosphoranylidene glutarimides. The Wittig reaction of 2 with several aldehydes in refluxing 1,2-dichloroethane affords the corresponding 2-alkylideneglutarimides 7 in 50-98% yield.
三苯基膦烯乙酰胺(1)与一些迈克尔受体反应,生成结晶的2-
三苯基膦烯戊二酰胺。将2与几种醛在回流的
1,2-二氯乙烷中进行维蒂希反应,可得到相应的2-烷基烯戊二酰胺7,产率为50-98%。
