摘要

A one-pot protocol toward several substituted 5, 6-dihydrobenzo [4, 5] imidazo [2, 1-a] isoquinolines 1 starting with 2-allylbenzaldehydes 2 was described. The process was carried out the one-pot condensation/hydroamination reaction of substituted 2- allylbenzaldehydes 2 with 1, 2-diaminobenzenes 3 in refluxing toluene in good yields. Skeleton 2 was prepared via one-pot ortho-metalative PhBCl2-mediated double alkylation ...
