Abstract

PURPOSE: To obtain the titled compound useful as a synthetic intermediate for drugs, agricultural chemicals, and industrial reagents in a short process readily and inexpensively, by dehydrohalogenating a reaction product of an acid halide and a (meth) allyl halide to carry out ring formation.
CONSTITUTION: An acid halide shown by the formula I (R is acyl group residue; X is halogen) is reacted with a (meth) allyl halide shown by the formula II (R' is H or methyl) in an inert solvent, e.g., haxane, CCl4, etc., in the presence of a Fridel-Craft catalyst (e.g., aluminum chloride, tin tetrachloride, etc.) to give a compound shown by the formula III. This compound shown by the formula III is subjected to ring formation using a dehydrohalogenating agent at 140W250°C, preferably 160W220°C, to give a substituted furan shown by the formula IV. A tertiary amine (e.g., collidine, tributylamine, etc.) is used as the dehydrohalogenating agent. The short process improves the total yield.
