This synthesis features the first application of iminium organocatalysis on an industrial scale. The key to the success of this organocatalytic transformation was the identification of a dual acid cocatalyst system, which allowed striking a balance of the 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 transmission of The first large-scale application of asymmetric iminium ion catalysis has been reported by Xu et al. at Merck as a key step in an improved process for synthesis of telcagepant (68, Scheme 12), a calcitonin gene-related peptide (CGRP) receptor antagonist indicated for the treatment of acute migraine. 67 A first generation route to the API suitable for pilot plant manufacturing had previously been developed (Scheme 12).
