Significance

Telcagepant is a candidate for the treatment of migraine because it antagonizes the calcitonin gene-related peptide (CGRP) receptor. The synthesis depicted (one of two reported) uses a rhodium-catalyzed Hayashi-Miyaura conjugate addition of an arylboronic acid to a nitroolefin as a key step. The synthesis produced multigram quantities of the target for clinical evaluation.
