Significance
(+)-Perophoramidine is an indole alkaloid isolated from Perophora namei with a complex multiring system, bisamidine functionality, and two vicinal quaternary centers. This is the first asymmetric synthesis with four racemic syntheses of perophoramidine or the related communesins previously published. The key step in this synthesis is the asymmetric hetero-Diels-Alder reaction controlled by a chiral auxiliary. This synthesis allowed the determination of the absolute configuration of the natural product.
