FATTY ACID DERIVATIVES AND THEIR USE

This disclosure concerns fatty acid derivatives, pharmaceutical compositions comprising the fatty acid derivatives, and methods of using the fatty acid derivatives, for example, to treat inflammation, chronic itch, chronic pain, an autoimmune disorder, atherosclerosis, a skin disorder, arthritis, a neurodegenerative disorder, or a psychiatric disorder in a subject. In some embodiments, the fatty acid derivative is a compound, or a stereoisomer, tautomer, or pharmaceutically acceptable salt thereof, having a structure according to: (I) wherein X is from 1-16 carbons in length, Z is aliphatic from 1-16 carbons in length, or is not present, Y is selected from: (II) R1, R2, and R3 are independently hydrogen or lower alkyl, R4 is lower alkyl, hydroxyl, carboxyl, or amine, R5 is hydrogen, lower alkyl, or halide, R6 is hydroxyl or substituted thiol, and each R7 is independently hydrogen or fluoride or is not present and the adjacent carbons form alkyne.

Synthetic studies toward A-74528

A potentially biomimetic approach toward the complex polyketide A-74528 is described. It is based on highly substituted biaryl compounds, synthesized using advanced cross-coupling and condensation methodologies.

1,5-Asymmetric induction of chirality: Highly diastereoselective addition reactions of organoaluminium reagents into ketone groups in the side-chain of π-allyltricarbonyliron lactone complexes

The utility of π-allyltricarbonyliron lactone complexes has been extended to include their use as chiral auxiliaries. Organoaluminium reagents add into ketone groups positioned in the side-chain of the allyl ligand to afford the corresponding tertiary alcohol complexes in good to excellent yield and with excellent diastereocontrol. Enantiomerically enriched complexes can be synthesised using the Sharpless asymmetric epoxidation protocol as the source of chirality. Addition products derived from endo ketones can be converted into the corresponding (E,E)-η4-dienetricarbonyliron complexes upon treatment with barium hydroxide solution without loss of diastereo- or enantio-purity.
