Allyltrimethylsilane and trimethylsilyl cyanide undergo smooth addition to N-acylated quinolines in the presence of a catalytic amount of iodine to afford 2-allyl- and 2-cyano-1,2-dihydroquinoline derivatives, respectively in good yields with high chemo- and regioselectivity. A variety of functional groups such as alkyl, alkoxy, halo, and nitro functionalities are tolerated under the reaction conditions
在催化量的碘存在下,将烯丙基三甲基硅烷和三甲基甲硅烷基氰化物平稳地加至N-酰化喹啉,分别以高收率和高化学选择性和区域选择性得到2-烯丙基-和2-氰基-1,2-二氢喹啉衍生物。在反应条件下可耐受多种官能团,例如烷基,烷氧基,卤素和硝基官能团。
