A new general synthesis of hydroxy- (5e-h) and methoxy- (5e-d) isoflavones has been accomplished in overall yields of 47-73percent from the corresponding 2-hydroxydeoxybenzoins (1a-h).The first step involves reaction with appropriate amounts of ethoxymeth
A New Synthesis of Isoflavanones

7-Methoxy-(3a)- and 5,7-dimethoxy-(3b)-isoflavanones have been synthesised in good yields by reacting corresponding o-hydroxydesoxybenzoins (1) with ethoxymethyl chloride in the presence of boiling acetone and dry potassium carbonate, followed by refluxing with ethanolic 4 percent aq. sodium carbonate.The products of the first step have been isolated as α-hydroxymethyldesoxybenzoins (2) and explanation of their formation is provided.
