  5-Exo versus 6-Endo Cyclization of Primary Aminyl Radicals:  An Experimental and Theoretical Investigation

  摘要：

  The cyclization of neutral primary pent-4-enylaminyl radicals was investigated experimentally and theoretically. Unlike the corresponding secondary aminyl radicals, primary pent-4-enylaminyl radicals underwent efficient cyclization to afford the pyrrolidine and/or piperidine products in good to high yields. While the simple pent-4-enylaminyl radical gave predominately the 5-exo, cyclization product, 4-chloropent-4-enylarninyl radicals led to the formation of the corresponding 6-endo cyclization products in excellent regioselectivity. Theoretical calculations revealed that the 5-exo cyclization rate of primary aminyl radicals is about 3-4 orders of magnitude higher than that of secondary aminyl radicals.

  The effective formation of 1-azabicyclo[3.1.0]hexane (5) by treatment of 2-(bromomethyl)pyrrolidine hydrobromide (4) with n-BuLi was established, with the reaction occurring by a rational reaction pathway via the open chain transition state 8 based on intermolecular Br...Li(+) coordination (SN2 process). The reaction of 5 with electrophiles 13a-n gave the corresponding pyrrolidines 14a-n and piperidine
