A straightforward synthesis of aminodibenzoxepines, new analogues of N-acetylcolchinol, is reported by using two different strategies. The first strategy involves a Grignard addition, a biaryl Suzuki− Miyaura coupling, and a HF-mediated cyclodehydration as key steps. A second strategy, better adapted to the synthesis of analogues bearing a benzylic substituent, was designed by inverting the order of the Grignard addition and the biaryl coupling. This ...
