    • Abstract

       

      Santal has been synthesised by methylating 5∶7∶3′∶4′-tetrahydroxy isoflavone with one mole of dimethyl sulphate. When three moles of dimethyl sulphate are employed santal dimethyl ether is obtained. An interesting observation has been made that demethylation of santal trimethyl ether under restricted conditions with hydriodic acid leads to the formation of a mixture of santal and nor-santal. They have been separated using aqueous sodium carbonate.
