A highly efficient, asymmetric synthesis of telcagepant (1), a CGRP receptor antagonist for the treatment of migraine, is described. This synthesis features the first application of iminium organocatalysis on an industrial scale. The key to the success of this organocatalytic transformation was the … Disclosed is an efficient synthesis for the manufacture of the caprolactam intermediate (3R,6S)-3-amino-6-(2,3-difluorophenyl)-1-(2,2,2-trifluoroethyl)azepan-2-one: Formula and salts thereof, and an efficient preparation of telcagepant using the caprolactam intermediate.

Telcagepant synthesis

Cui and associates (2015) stated that calcitonin gene-related peptide (CGRP) receptor antagonists, such as telcagepant, have been under investigation as a treatment for acute migraine. In a meta-analysis, these researchers evaluated the effectiveness of telcagepant versus placebo and triptans (zolmitriptan or rizatriptan). A highly efficient, asymmetric synthesis of telcagepant (1), a CGRP receptor antagonist for the treatment of migraine, is described. This synthesis features the first application of iminium organocatalysis on an industrial scale.

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).
