N -Arylmethylene-2-naphthylamines react with acetylcyclohexane and 1-acetylcyclohexene under mild conditions to afford 2-aryl-2-(2-naphthylamino)ethyl cyclohexyl and 1-cyclohexenyl ketones, respectively. Under more severe conditions (110°C), the reaction is accompanied by cyclization with formation of 3-aryl-1-cyclohexyl(or 1-cyclohexenyl)benzo[ f ]quinolines. Proper choice of the amount of catalyst
N- 芳基亚甲基-2-萘胺在温和条件下与乙酰基环己烷和1-乙酰基环己烯反应,分别得到2-芳基-2-(2-萘基氨基)乙基环己基和1-环己烯基酮。在更苛刻的条件下(110℃),反应伴随环化,形成3-芳基-1-环己基(或1-环己烯基)苯并[ f ]喹啉。催化剂,温度和反应时间的量的适当选择允许中间体3-芳基-1-环己基(或1-环己烯基)-3,4-二氢苯并[隔离 ˚F 〕喹啉。
