The 5/7-, 5/8- and 5/9-bicyclic lactams 3, 17, 5 and 6 have been synthesised as single diastereoisomers by a route involving ring closing olefin metathesis. The X-ray crystal structure of the amino acid hydrochloride 17 has been carried out and compared to that of the saturated external β-turn constraint 18.

NHC-Catalyzed Intramolecular Redox Amidation for the Synthesis of Functionalized Lactams
A very efficient NHC-catalyzed lactamization reaction is reported. For most cases, the ringexpansion reaction proceeds to cleanly furnish five- and six-membered N-Ts and N-Bn lactams, without the need for further purification. Evidence is presented suggesting a dual role for the stoichiometric base: (1) deprotonation of the triazolium precatalyst and (2) activation of the nitrogen leaving group through
