Abstract

The effective formation of 1-azabicyclo [1.1. 0] butane (2) by treatment of 2, 3- dibromopropylamine hydrobromide (1) with n-BuLi could be understood considering a rational reaction pathway via both transition states 10 and 19 based on the intramolecular Br··· Li+ coordination. A similar cyclization pathway starting from N-benzyl-3- bromopropylamine hydrochloride (17) to afford N-benzylazetidine (18) could also be ...
