Abstract
A short and effective strategy for the construction of the tetracyclic core structure of the biologically active compound benzomalvin A from cheap commercially available (S)-phenylalanine and isatoic anhydride is described. This three-pot methodology was successfully implemented to synthesize N-demethylbenzomalvin A on a multi-gram scale with 54% overall yield.
