3-Substituted-hex-1-en-5-ynes were cyclized by treatment with diethylaluminum hydride; in hydrocarbon/ether solvent, -2-substituted-methylcyclopentane is produced, while in the absence of ether, the product is 2-substituted-methylenecyclopentane. Yields are 69% to 76%.
通过用氢化二乙基铝处理使3-取代的1-己-1-烯-5-炔环化;在烃/醚溶剂中,产生-2-取代的甲基环戊烷,而在不存在醚的情况下,产物为2-取代的亚甲基环戊烷。产率为69%至76%。
