    • Abstract

       

      The condensation of 1: 2: 3: 5-tetrahydroxy benzene with anisoyl acetaldehyde takes place in an abnormal way and gives rise to 5: 7: 8-trihydroxy-4′-methoxy flavylium chloride. By using 2: 6-dibenzyloxy quinol, 5: 7-di-benzyloxy-6-hydroxy-4′-methoxy flavylium chloride is obtained and subsequent debenzylation yields carajurone hydrochloride; by the action of sodium acetate, the colour-base carajurone is obtained.
