Abstract
A new procedure for the synthesis of 2-azabicyclo [3.3. 1] nonanes by intramolecular carboradical cyclization of 4-(trichloroacetamido) cyclohexenes substituted with an electron withdrawing substituent (ester or nitrile) is described. The procedure allows the preparation of synthetically interesting azabicyclos 14 and 15 in nearly 70% yield.
