N-Arylmethyl-7-azabicyclo[2.2.1]heptane ( I) derivatives have been synthesized by deprotection of N-protected, N-(arylmethyl)cyclohex-3-enamines, bromination of the resulting secondary cyclohex-3-enamines, followed by base-promoted cyclization (route a), or by bromination of N-protected, N-(arylmethyl)cyclohex-3-enamines followed by deprotection and base-mediated cyclization (route b). In these protocols we have observed that the bromination of the key intermediates ( 12, 13, and 19) is stereoselective leading to major trans-3- cis-4-dibromides ( 14, 17, and 20), whose mild base-mediated heterocyclization (on compound 14), or the two-step acid hydrolysis plus base-promoted cyclization (on compounds 17 and 20), gave products 6 and 7 in good yield. A mechanistic investigation using DFT has been carried out to explain the results observed in this work.
