Abstract
PURPOSE: To prepare the title compound useful as a raw material of pharmaceuticals, or intermediate of perfumery, in high yield, by reacting a phenol compound and glyoxylic acid with cyclodextrin, etc. in a basic aqueous medium.
CONSTITUTION: A compound III [Y is H, CH(OH)-COOH], IV, V or VI, is prepared by reacting 1 mole of a phenol compound I (R1 is OH, lower alkoxy) or II (R2 is lower alkyl), e.g. catechol, resorcinol, with 0.5W1 mole of glyoxylic acid in a basic aqueous solvent in the presence of ≥0.001g, based on 1 g of the phenol compound, of cyclodextrin or starch, at 0W50°C
