Abstract
PURPOSE:To readily obtain the titled compound in high yield and optical purity, by reducing (R)-(+)-gamma-butylolactone-gamma-3-propionic acid-tert.-butyl ester using a specific metal hydride at excess amount and then subjecting the reduced product to acid treatment. CONSTITUTION:(R)-(+)-gamma-Butylolactone-gamma-3-propionic acid-tert.-butyl ester expressed by formula I (t-Bu is tert.-butyl) is reacted with at least one kind of metal hydride selected from LiBH4, LiAlH4, hydrogenated bis(2- methoxyethoxy)aluminum and NaBH2S3 used at an amount of 0.5-1.5mol. based on 1mol. compound expressed by formula I in an organic solvent such as anhydrous tetrahydrofuran at 0-25 deg.C for 3-15hr and reduced to afford (-)-(4,7)-dihydroxyheptanoic acid-tert.-butyl ester, which is then subjected to acid treatment with an acid such as dilute hydrochloric acid or formic acid at ambient temperature for 3-8hr while stirring to provide the aimed compound expressed by formula III useful as a raw material for perfume, etc.
