Carotinoid intermediate compound, preparing method thereof, and method for preparing carotinoid compound, astaxanthin and astacene using the same

摘要

The present invention relates to a carotenoid intermediate compound, a method for preparing the same, and a method for producing a carotenoid compound using the same. More specifically, the present invention relates to a carotenoid compound, which is harmless to humans, and is added to feed for pigmentation of cultured fish. It relates to a method for producing astaxanthin (astaxanthin) which is a kind and an astaxin (astacene) which is an oxide of astaxanthin. According to the present invention, the sulphate chemistry of Julia is used to oxidize a carbon adjacent to a ketone group from a C40 ketone compound which is efficiently used for the synthesis of canthaxanthin to form a hydroxyl group (-OH) or an ether thereof ( After forming a compound attached with an ether) binding derivative, astaxanthin or astaxine can be efficiently synthesized by sequentially applying the Lambberg-Backlund reaction and the dehydrosulfonation reaction. have.;Carotenoids, carotene, astaxanthin, astaxin, sulfone compounds, lambberg-backclund reactions
