3-Methyl-2-butenenitrile (1) cyclodimerised on treatment with lithium diisopropylamide in dimethoxyethane at temperatures between −78°C and 0°C to 3-amino-4-cyano-1,5,5-trimethyl-1,3-cyclohexadiene (2) the structure of which was established by acid hydrolysis to the known 4-cyano-1,5,5-trimethyl-1-cyclohexene-3-one (3).
在二甲氧基乙烷中,于-78°C至0°C的温度下,在二甲氧基乙烷中用二异丙基氨基锂处理,将3-甲基-2-丁烯腈(1)环化成3-氨基-4-氰基-1,5,5-三甲基-1,3-环己二烯(2)的结构是通过酸水解为已知的4-cyano-1,5,5-trimethyl-1-cyclohexene-3-one(3)来建立的。
