摘要:The subject invention provides methods for the chemical synthesis of racemic arsinothricin (D,L-AST), the novel organoarsenical antibiotic. One is by condensation of the 2-chloroethyl(methyl)arsinic acid with acetamidomalonate, and the second involves reduction of the N-acetyl-protected derivative of hydroxyarsinothricin (AST-OH) and subsequent methylation of the resulting sodium salt of trivalent arsenic intermediate with methyl iodide. The enzyme AST N-acetyltransferase (ArsN1) was utilized to purify L-AST from racemic AST. This expedient chemical synthesis of AST provides a source of this novel antibiotic for future drug development.

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:WHEREIN X is an integer having a value from 2 to 6 inclusive and Y is an integer having a value from 2 to 8 inclusive. It also provides for new methods of making compounds useful in the synthesis of zearalanone and related compounds. The new compounds useful as intermediates are 2,7-octadienoic acid; methyl 2,7-octadienoate; sodium ethyl 6-(4-pentenyl)- Beta -dihydroesorcylate; ethyl 6-(4-pentenyl)- Beta dihydroresorcylate; sodium methyl 6-(4-pentenyl)- Beta dihydroresorcylate; methyl 6-(4-pentenyl)- Beta dihydroresorcylate; methyl 3-bromo-6-(4-pentenyl)- Beta dihydroresorcylate; methyl 6-(4-pentenyl)- Beta -resorcylate; ethyl 6-(4-pentenyl)- Beta -resorcylate; ethyl 6-(4-pentenyl)Beta -resorcylate dibenzyl ether; tetrahydropyran-2-yl 4-penten2-yl ether; ethyl 6-(6-oxo-10-tetrahydropyran-2-xyloxyundecyl)Beta -resorcylate dibenzyl ether; and 6-(10-hydroxy-6oxounderyl)- Beta -resorcylic acid dibenzyl ether. Methods for preparing these intermediates are also disclosed. This invention provides a new synthesis for zearalanone and for related compounds having more or fewer carbon atoms in the nonaromatic ring than does zearalanone, which related compounds and zearalanone are represented by the formula

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.

标题 :2-position modification for synthesis of resorcinol scaffolding

权利人:CANOPY HOLDINGS LLC
摘要:A resorcinol with modifications at the 2-position is provided. The reactant resorcinol may have a variety of functional groups at each of the 1, 3, and 5 position such as a hydroxide, a lower alkyl group, a phenyl, a substituted phenyl, a lower alkenyl, or a lower alkynyl sp 2 carbon group (e.g., substituted phenyl, vinyl), sp (e.g., alkyne), hydrogen. The resorcinol is modified at the 2-position with a nucleophile or an electrophile. The resulting resorcinol may serve as a stable intermediate for the synthesis of cannabinoid or cannabinoid derivatives.
