Abstract
PURPOSE: The mutual reaction of (5-substituted-2-furyl)hydroxymethane derivative is conducted in the presence of an acid in water and/or an inert organic solvent to produce title compound used as intermediate of medicines and agricultural chemicals.
CONSTITUTION: The mutual reaction of a compound of formula I (R, R' are 1W5C alkyl, 3W5C alkenyl with a double bond on the terminal) is carried out in the presence of an acid, e.g., hydrochloric acid, in water or an inert organic solvent, e.g., dioxane, or their mixture, usually at 10W100°C, preferably 30W80°C to give the objective compound of formula II in a very short time with no complicated operations in high yield. The compound of formula I is obtained by, e.g., reaction of a 5-substituted furfural with a Grignard reagent in high yield. The amount of the acid used is 1W500pts.wt. per 1000 parts of the compound of formula I.
