BUTYROLACTONE COMPOUND, AND PRODUCTION METHOD

摘要

Provided are: a novel production method for inexpensively producing, in high yield, a photopolymerizable compound used in liquid crystal display elements or the like; and a novel intermediate compound. In a method for producing a compound represented by formula (1), a compound represented by formula (A) is reacted with a compound represented by formula (C), under acidic conditions, in the presence of metallic tin or a tin-containing compound. In a method for producing a compound represented by formula (2-A), the compound represented by formula (1) is reacted with a compound represented by formula (D), in the presence of a base. Also provided are the compound represented by formula (1) and the compound represented by formula (2-A). (In the formulae: n represents 1 or 2; J1 and J2 represent halogens; R represents a C1-6 alkyl group; Y1 represents -SO2-R2; and R represents a hydrocarbon group.)
