Abstract

PURPOSE: To obtain a monoformylated plenol with a high selectivity, by reacting a phenol with glyoxilic acid in a mixed solvent of water and an alcohol in a specific proportion under basic conditions at about ordinary temperature, and by oxidizing the reaction product thus obtained.
CONSTITUTION: A phenol of formula I: (X is 1W3C alkyl or alkoxyl group), e.g. 2-methoxyphenol, etc. is reacted with glyoxylic acid in a mixed solvent of water (W) and a 1W4C alcohol (A) at a weight ratio of A to W of 0.05W2:1 under basic conditions at 0W50°C,preferably 10W40°C to give a compound of formula II. After recovering the reaction solvent alcohol and unreacted phenol from the reaction mixture if possible, the compound of formula II is oxidized to give a monoformylated phenol, e.g. 4-hydroxy-3-methoxybenzaldehyde, etc.
USE: An intermediate for perfumes and medicines.
