Cycloclavine is an ergot alkaloid. It was first isolated in 1969 from seeds of Ipomoea hildebrandtii vatke.[1] The first total synthesis of (±)-cycloclavine was published in 2008 by Szántay.[2] Further reports came from Wipf and Petronijevic,[3] Cao[4] and Brewer.[5] In 2016, Wipf and McCabe completed an 8-step asymmetric synthesis of (-)-cycloclavine.[6]
