Annulation of pyrrole: application to the synthesis of indolizidine alkaloids
摘要:
The nucleophilicity of pyrrole has been exploited to rapidly assemble the bicyclic skeleton of the indolizidine alkaloids. The key sequence is the annulation of a second ring onto pyrrole from a gamma-lactone and has been exploited in the synthesis of the natural products monomorine and (+/-)-indolizidine 209D.
