Cycloclavine
Webcycloclavine was derived through a stereoselective intramolecular [4+2] cycloaddition of a methylenecyclopropane. The fourth section describes an approach towards the total synthesis of cyclopiazonic acid. A promising route to this alkaloid was established, including a rapid construction of the WebLysergic acid hydroxyethylamide. D-Lysergic acid α-hydroxyethylamide ( LSH, LAH ), also known as D-lysergic acid methyl carbinolamide, is an alkaloid of the ergoline family, believed to be present in small amounts in various species in the Convolvulaceae (morning glory), as well as some species of fungi .
