Abstract
The first asymmetric total synthesis of (-)-hibiscone C and a concise synthesis of ergot alkaloid lysergine are described. Both syntheses were achieved using the radical cyclization/fragmentation strategy. This cascade reaction enabled the application of the strained bicycle as a synthon for the synthesis of highly substituted decalins in an efficient and stereoselective manner.
