Abstract

Ascorbic acid and hydroxytetronic acid may be thought of as dihydroxydihydrofuranones. Their activity is greatly increased by the substitution of a phenyl group for the dihydroxyethyl group of ascorbic acid. The corresponding imides are active developers. Superadditivity is obtained with combinations of the several dihydroxydihydrofuranones and -furimides with aminophenols and pyrozolidinones.
