Abstract

PURPOSE:To obtain the title compound in high yield in one stage, by reacting readily available and safe 3,9-bis(2-hydroxyethyl)-2,4,8,10-tetraoxaspiro(5,5)undecane with phenylhydrazine under specific conditions. CONSTITUTION:3,9-Bis( 2-hydroxyethyl )-2,4,8,10-tetraoxaspiro( 5,5 )undecane (CATU) is reacted with phenylhydrazine (P), preferably in water as a reaction solvent, at 75-120 deg.C under acidic conditions to give indole-3-acetic acid. Preferably, an inorganic acid, e.g. hydrochloric or sulfuric acid, an organic acid, e.g. p- toluenesulfonic acid, or a Lewis acid, e.g. zinc chloride, may be used to keep the reaction system acidic. The molar amount of P is 2 times or more that of CATU. USE:A plant growth regulator itself, and also usable as a raw material for various agricultural chemicals or medicines.
