Abstract
Summary Though the benzophenone method of synthesis is not quite advantageous for dalbergin and methyl dalbergin, it is more convenient for the preparation of allo-dalbergin (4- phenyl-5-methoxy-6-hydroxy coumarin) and its methyl ether. These compounds and other 4- phenyl coumarins give markedly coloured solutions when treated with alcohol, hydrochloric acid and magnesium; a number of 4-methyl coumarin derivatives also give similar colour ...
