摘要:A method used for synthesizing intermediates for use in the synthesis of carotenoids and carotenoid analogs, and/or carotenoid derivatives. In some embodiments, the invention includes methods for synthesizing optically active intermediates useful for the synthesis of optically active carotenoids. Synthesis of optically active carotenoids, in one embodiment, may be accomplished by forming an optically active dihydroxy intermediate from ketoisopherone. The optically active dihydroxy intermediate may be converted into optically active astaxanthin derivatives.

权利人:ARIGEN PHARMACEUTICALS INC; SAIMOTO HIROYUKI; HAGA YASUSHI
摘要:In the synthesis of ascofranone, a compound represented by formula (III), (IV), (V) or (VII) or an optical isomer thereof is used as an intermediate for the synthesis. [In the formulae, R 1 and R 2 independently represent a hydrogen atom, a C 1-7 alkyl group, a phenoxyalkyl group having a halogen atom on a carbon atom in a benzene ring therein, or a phenyl group having a C 1-7 alkoxy group or a C 1-7 alkoxycarbonyl group on a carbon atom in a benzene ring therein; and X represents a halogen atom or a group R 5 SO 3 (wherein R 5 represents a C 1-7 alkyl group or a phenyl group having a C 1-7 alkyl group on a carbon atom in a benzene ring therein).] By using the compound, it becomes possible to reduce the number of steps required for the total synthesis of ascofranone to 7 or 8 from 12 which is a number of the steps required for the conventional ascofranone total synthesis processes.
