The invention relates to lipid compounds of formula (I) and their pharmaceutically acceptable salts for the prevention and/or treatment of ophthalmic disorders such as retinal degenerative disorders and ocular inflammatory diseases: (I) (wherein R1 is either a C9 to C22 alkyl group, or a C9 to C22 alkenyl group having from 1 to 6 double bonds; R2 is selected from the group consisting of a halogen atom, a hydroxy group, an alkyl group, an alkoxy group, an alkylthio group, a carboxy group, an acyl group, an amino group, and an alkylamino group; R3 is a hydrogen atom, or a group R2; R4 is a carboxylic acid or a derivative thereof; and X is methylene (-CH2-), or an oxygen or sulfur atom).
A silver‐catalyzed decarboxylative trifluoromethylthiolation of secondary and tertiary carboxylic acids under mild conditions tolerates a wide range of functional groups. The reaction was dramatically accelerated by its performance in an aqueous emulsion, which was formed by the addition of sodium dodecyl sulfate to water. It was proposed that the radical, which was generated from the silver‐catalyzed

A process for synthesizing (R)-3 -hy droxybutyl (R)-3 -hy droxybutanoate from ethyl (R)-3-hydroxybutanoate and (R)-l,3-butanediol, as well a process for synthesizing (R)-3-hy droxybutyl (R)-3-hy droxybutanoate from (R)-3-hydroxybutyric acid and (R)-l,3-butanediol. Also provided are processes for isolating (R)-3-hy droxybutyl (R)-3-hy droxybutanoate, including from a fermentation broth.
The present invention is directed to a novel taste-masking composition comprising a taste-masking effective amount of an
