Synthetic studies towards an advanced precursor of the jatrophane diterpene Pl-4

Jatrophane diterpenes, isolated from members of the Euphorbiaceae­ plant family, constitute a class of biologically and structurally intriguing natural products. Herein, different strategies for the preparation of an advanced intermediate towards the total synthesis of the jatrophane diterpene Pl-4 are described. Key strategies for the elaboration of the jatrophane precursors include hydrometalation and radical reactions.
