Synthesis of (-)-Cryptopleurine by Combining Gold(I) Catalysis with a Free Radical Cyclization

2015

(R)-(–)-Cryptopleurine, a highly cytotoxic alkaloid found in Cryptocarya and Boehmeria species, was synthesized in high optical purity using a gold(I)-NHC catalyzed cyclization of an unsymmetrical phenanthrene precursor combined with a free radical cyclization to achieve closure of the C-ring.

No. of bitstreams: 0 Previous issue date: 2013-02-07 Background: Functional redundancy has been debated largely in ecology and conservation, yet we lack detailed empirical studies on the roles of functionally similar species in ecosystem function. Large bodied frugivores may disperse similar plant species and have strong impact on plant recruitment in tropical forests. Th…
