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: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.

摘要:Synthesis of enantiopure cis-α-irone from a renewable carbon source Disclosed herein are natural and synthetic enzymes capable of performing a method of producing cis-α-irone. The method comprises providing an enzyme capable of converting psi-ionone to cis-α-irone; and contacting the enzyme and psi-ionone under suitable conditions to produce cis-α-irone. The enzyme may be a methyltransferase from Streptomyces albireticuli (SaMT), a promiscuous bifunctional methyltransferase/cyclase (pMT1) enzyme from Streptomyces, or a modified pMT1 enzyme with at least one substitution. The enzymes allow the in-vivo and in-vitro production of cis-α-irone including the use of glucose as feedstock for the biotransformation into cis-α-irone.

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.

标 题 :Sulfoxide ligand metal catalyzed oxidation of olefins

摘要:The enantioselective synthesis of isochroman motifs has been accomplished via Pd(II)-catalyzed allylic C—H oxidation from terminal olefin precursors. Critical to the success of this goal was the development and utilization of a novel chiral aryl sulfoxide-oxazoline (ArSOX) ligand. The allylic C—H oxidation reaction proceeds with the broadest scope and highest levels asymmetric induction reported to date (avg. 92% ee, 13 examples ≥90% ee). Additionally, C(sp 3 )-N fragment coupling reaction between abundant terminal olefins and N-triflyl protected aliphatic and aromatic amines via Pd(II)/sulfoxide (SOX) catalyzed intermolecular allylic C—H amination is disclosed. A range of 52 allylic amines are furnished in good yields (avg. 76%) and excellent regio- and stereoselectivity (avg. >20:1 linear:branched, >20:1 E:Z). For the first time, a variety of singly activated aromatic and aliphatic nitrogen nucleophiles, including ones with stereochemical elements, can be used in fragment coupling stiochiometries for intermolecular C—H amination reactions.
