Total Synthesis of (±)-Sceptrin
Long Nguyen, Timothy F. Jamison
Abstract
A four-step synthesis of the dimeric pyrrole-imidazole alkaloid sceptrin is reported. The brevity of the route is based on a simple solution developed for selective assembly of the cyclobutane core of the natural product. The photochemical intermolecular [2 + 2] dimerization of a useful hymenidin surrogate enables direct entry to this enigmatic class of biologically active marine secondary metabolites.
