Diterpenes from Jamaican Caesalpiniaceae and Euphorbiaceae [Caesalpinia and Croton spp.]

Two new ceasalpins, F and G were extracted from Caesalpinia bonducella, a plant used in folk-medicine, and their structure and stereochemistry described. The chemistry of the crotofolanes, isolated from Croton corylifolius was reviewed and a reinvestigation resulted in the isolation of a new crotofo...

Summary:Two new ceasalpins, F and G were extracted from Caesalpinia bonducella, a plant used in folk-medicine, and their structure and stereochemistry described. The chemistry of the crotofolanes, isolated from Croton corylifolius was reviewed and a reinvestigation resulted in the isolation of a new crotofolane diterpene crotofolin E. It was found to be highly functionalised and contained the rare pseudo-acid moiety. The known compounds crotofin C, corylifuran, B-sitosterol and 5-hydroxy-3,6,7,3, 4 pentamethoxyflavone were also isolated and elucidated. In a third investigation three diterpenes from Croton nitens were isolated and characterised: 2 new Kaurene diterpenes and a casbenoid diterpene. The latter, only the second such molecule to be isolated is believed to provide the missing link in the proposed biogenesis of diterpenes isolated from the family Euphorbiaceae
