摘要：

Starting from (R)-1-(2-methoxyphenyl)ethylamine, the title compounds were synthesized, Key steps are a diastereoselective imine alkylation and a Pd-catalyzed biaryl coupling. The benzylic stereogenic centers of the (5R,7R)-azepine induce a strong bias for the atropisomeric conformer having aS axial chirality and pseudo equatorial Me groups.
