The synthesis featured an enantioselective 1,4-addition of nitromethane, which is the first application of … Asymmetric Synthesis of Telcagepant, a CGRP Receptor Antagonist for the Treatment of Migraine Feng Xu,* Michael Zacuto, Naoki Yoshikawa, Richard Desmond, Scott Hoerrner, Tetsuji Itoh, Michel Journet, Guy Humphrey, Cameron Cowden, Neil Strotman, Paul Devine Department of Process Research, Merck Research Laboratories, Rahway, NJ 07065, USA 2006-10-26. Telcagepant has been investigated for the treatment of Migraine. It is an antagonist of the receptor for calcitonin gene-related peptide (CGRP), a primary neuropeptide involved in the pathophysiology of migraine. CGRP and its receptors are found in areas of the central and peripheral nervous system that are important for the The first large-scale application of asymmetric iminium ion catalysis has been reported by Xu et al.

Second part of the synthesis of Telcagepant. Cyclisation involved the employment of a mixed anhydride, possible for the decreased nucleophilicity of the trifluoroethyl nitrogen, and was followed by a base promoted dynamic crystallisation process in aqueous NaOH/DMSO mixture, which allowed the isolation of the 2-acetamido caprolactam 60 in 73% overall yield from the enamide.
