High-performance liquid chromatographic separation and spectral identification of the photoreaction products of methyl 5,8-epoxyretinoate.
Photoreaction of methyl 5,8-epoxyretinoate was investigated. Irradiation of methyl 5,8-epoxyretinoate in acetonitrile with a light from a high-pressure mercury lamp or a daylight fluorescent lamp afforded three new products, which were purified by high-performance liquid chromatography. They were characterized on the basis of spectroscopic data as 11-(Z), 13-(Z), and 11,13-di(Z) isomers, respectively.
