摘　　要：报道了液晶中间体４－烷基环己酮（Ｃ３～Ｃ７）的合成新方法及实验结果。它以醛为基本原料，制成烯胺后，与丁烯酮加成、缩合、加氢而得。方法简便，周期短，产率高。A new synthetic method for 4 alkylcyclohexones (C 3～C 7) as intermediates of liquid crystal is reported.They were prepared by the Diels Alder adduct reaction of enamines with methyl vinyl ketone, then by the condensation and catalytic hydrogenation. The enamines were prepared from aldehydes which were used as the base material.The method is simple and convenient,with short reaction time and high yield.
