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.

摘要:A method for synthesizing intermediates for use in the synthesis of carotenoid synthetic intermediates, carotenoid analogs, and/or carotenoid derivatives. The carotenoid analog, derivative, or intermediate may be administered to a subject for the inhibition and/or amelioration of any disease that involves production of reactive oxygen species, reactive nitrogen species, radicals and/or non-radicals. In some embodiments, the invention may include methods for synthesizing chemical compounds including an analog or derivative of a carotenoid. Carotenoid analogs or derivatives may include acyclic end groups. In some embodiments, a carotenoid analog or derivative may include at least one substituent. The substituent may enhance the solubility of the carotenoid analog or derivative such that the carotenoid analog or derivative at least partially dissolves in water.

摘要:1,5-disubstituted-2-hydroxy-gibbatetraen-6-ones are useful as estrogen receptor modulators and as precursors to estrogen receptor modulators. The current invention provides a method for the synthesis of 1,5-disubstituted-2-hydroxy-gibbatetraen-6-ones from simple indanone starting materials via a Robinson-type annulation followed by an internal alkylation reaction. This invention further describes the novel use of a fluoroethyl substituent as a latent alkylating group for an internal cyclization reaction.
