Abstract

A few 4-hydroxy-3-phenylcoumarins have been synthesised from 2-hydroxy deoxybenzoins by condensing them with diethyl carbonate in the presence of sodium. By the reaction of the same deoxybenzoins with ethylorthoformate in the presence of pyridine and piperidine a few isoflavones have also been prepared. The bacteriostatic and fish-toxic properties of these compounds have been evaluated.
