Abstract

A convenient, high-yield synthesis of N-Boc-7-azabicyclo[2.2.1]hept-5-en-2-one (7) was developed by SmI2-mediated desulfonylation of 6. Thus, 5-endo-, 5-exo-, 6-endo-, and 6-exo-hydroxylated epibatidine analogues 2a,b and 3a,b were synthesized from 7 by using a Pd(PPh3)4-catalyzed reductive Heck coupling reaction and SmI2-mediated reduction of the carbonyl group as the key steps. Other reaction conditions for the reductive Heck procedure and the reduction step were also investigated.
