The title compound 1 (NPP) is prepared from formaldehyde, nitromethane, an pivaloyl chloride. It is shown to be a versatile nitroallylating reagent combining with nucleophiles as different as anilines, indoles, enolates, and organolithium compounds. This is documented by ca. 40 examples (2–30). The mechanism of the reaction is discussed. Some examples of addition of two different nucleophiles to the
由甲醛,硝基甲烷,新戊酰氯制备标题化合物1(NPP)。它被证明是一种与苯胺,吲哚,烯醇盐和有机锂化合物等不同的亲核试剂结合的通用硝基烯丙基化试剂。这由ca记录。40个示例(2–30)。讨论了反应机理。描述了将两种不同的亲核试剂加到NPP的C 3-部分上的一些实例(35-46)。这证明了NPP作为收敛性合成的多重偶联剂的有用性,对于不含硝基的产物也是如此((方案4))。
