Synthesis of 2-azabicyclo[3.3.1]lnonanes by means of (carbamoyl)dichloromethyl radical cyclization

Quirante, Josefina,Escolano, Carmen,Massot, Mireia,Bonjoch, Josep

, p. 1391 - 1402 (2007/10/03)

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 tester or nitrile) is described. The procedure allows the preparation of synthetically interesting azabicyclos 14 and 15 in nearly 70% yield.
