    • Abstract

       

      The structure of 6-methoxy-4 ∶ 5 ∶ 7-trihydroxy-benzal-coumaranone was suggested by Saloojaet. al.3 for one of the forms of pedicinin. A substance of this constitution has now been synthesised by applying the two stage process of nuclear oxidation to an appropriate compound of the benzalcoumaranone series. The synthetic product differs markedly from pedicinin. Similar difference has been noticed earlier with the flavanone isomer, allo-pedicinin. It is concluded therefore that the two melting points noted for pedicinin are due to the existence of two crystal forms.
