Cycloclavine

Cycloclavine is an ergot alkaloid. It was first isolated in 1969 from seeds of Ipomoea hildebrandtii vatke. The first total synthesis of (±)-cycloclavine was published in 2008 by Szántay. Further reports came from Wipf and Petronijevic, Cao and Brewer. In 2016, Wipf and McCabe completed an 8-step asymmetric synthesis of (-)-cycloclavine.
