Title:
METHOD FOR PRODUCING 2-ALLYLCARBOXYLIC ACID COMPOUND
Document Type and Number:
WIPO Patent Application WO/2006/075596
Kind Code:
A1
Abstract:
Disclosed is a method for commercially advantageously producing a 2-allylcarboxylic acid with high yield. Specifically disclosed is a method for producing a 2-allylcarboxylic acid compound which is characterized by the process wherein a compound represented by the formula (I) below is reacted in the presence of an acid catalyst and an allyl alcohol, thereby obtaining a 2-allylcarbonyl compound represented by the formula (II) below, and then the thus-obtained 2-allylcarbonyl compound is converted into a 2-allylcarboxylic acid represented by the formula (III) below. [Chemical formula 1] (I) [Chemical formula 2] (II) [Chemical formula 3] (III) (In the above formulae, bonds shown by solid and dotted lines represent a single bond or a double bond; X represents a formyl group, a dialkoxymethyl group or a trialkoxymethyl group; and Y represents a hydrogen atom or an alkoxy group.)
