    • Abstract

       

      2: 4 Resorcylaldehyde undergoes condensation with malonic acid giving umbelliferon or umbellic acid according to the conditions. The yield is as expected lower than the lowest obtained with mono-hydroxybenzaldehydes.

      A trace of pyridine gives better yield than any method, except that the yield is slightly higher when glacial acetic acid is used in place of a base.
