Described is a totalsynthesis of the related alkaloids, cyclopiamide A and speradine E, via a unified strategy that also delivers the natural product aspergilline A. Key steps include metal-free conversion of a malonyl chloride and propargylamine to an intermediate pyrrolinone and a palladium catalyzed decarboxylation/aromatization sequence that delivers the requisite tetracyclic core.
