Junionone is the first monocyclic cyclobutane monoterpenoid isolated from a plant. Of the existing four syntheses of this compound, none employs a ketene cycloaddition to construct the four-membered ring. Herein, we report the first total synthesis of junionone that features a ketene cycloaddition for the synthesis of this compound, starting from the… CONTINUE READING
