(–)-Steganone was formally synthesized by using the diastereoselective ortho-lithiation of a chiral acetal of tricarbonyl(3,4,5-trimethoxybenzaldehyde)chromium and subsequent cross-coupling of optically pure tricarbonyl(2-bromo-3,4,5-trimethoxybenzyl alcohol)chromium with arylboronic acid as key steps.
