A methodology for the synthesis of 7,12-dihydro-5H-6,12-methanodibenzo[c,f]azocines from aromaticaldehydes and N-(methoxymethyl)-N-(trimethylsilylmethyl)benzylamine using catalysis by trifluoroacetic and perchloric acids is described. The developed protocol was applied for the synthesis of N-unsubstituted and N-methyl-4-aryltetrahydroisoquinolines.
