A methodology for the synthesis of 7,12-dihydro-5H-6,12-methanodibenzo[c,f]azocines from aromatic aldehydes 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.

New synthetic equivalents, N-methoxy-N-methyl-N′-phenylsulfonyl glycinamide and N-methoxy-N-methyl-N′-benzyl-N′-tert-butyloxy carbonyl glycinamide based on WA functionality were developed for the convenient synthesis of 4-aryl-1,2,3,4-tetrahydroisoquinoline framework. Two simple reactions, N-benzylation and addition of arylmagnesium halide on the WA functionality of the former afforded the key intermediate for convenient synthesis of N-phenylsulfonyl protected 4-aryl-1,2,3,4-tetrahydroisoquinoline, through reduction and acid promoted cyclization. With the latter, the addition of arylmagnesium halide on the WA functionality followed by the same protocol afforded the direct synthesis of 4-aryl-1,2,3,4-tetrahydroisoquinolines in good yields. The acid promoted cyclization step enabled concomitant removal of N-Boc protection.
