    • Abstract

       

      The position of the methoxyl group in dalbergin has been established by synthesis using two methods: (1) partial methylation of 4-phenyl-aesculetin and (2) nuclear oxidation of 4-phenyl umbelliferone methyl ether. By similar methods the 7-benzyl ether of 4-phenyl aesculetin and from it by methylation and debenzylation iso-dalbergin has been prepared. The ethyl ethers of dalbergin and iso-dalbergin have also been obtained.
