A convenient synthesis of 5-methoxyfuroflavone (6, pongaglabol methyl ether), a constituent of some Pongamia or Millettia genus, was achieved by starting from 2,4-dihydroxy-6-methoxyacetophenone via a chalcone precursor, followed by treatment with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ). This five-step reaction (total yield: 21.6%) is more facile with that of previously utilized procedures
