of functionalised dienes and trienes have been prepared by one-pot processes in which alcohol oxidation is accompanied by in situ Wittig homologation using Trippett’s reagent [(triphenylphosphoranylidene)acetaldehyde] followed by addition of a second stabilised phosphorane. This procedure has been applied to α-hydroxy carbonyl compounds and activated benzylic alcohols.
通过一锅法制备了一系列官能化的二烯和
三烯,其中使用Trippett试剂[(三苯基
磷酰亚烷基)
乙醛]伴随醇氧化并进行原位Wittig同源化,然后加入第二种稳定的正膦烷。该方法已经应用于α-羟基羰基化合物和活化的
苄醇。
