METHOD FOR SYNTHESIZING A PRECURSOR OF A SINGLE DAIRY-LACTONE ISOMER

This disclosure provides a method for preparing a precursor of a single dairy-lactone isomer, methods of preparing a single dairy-lactone isomer, and to the organoleptic uses thereof.

Adrenaline profiling of lipases and esterases with 1,2-diol and carbohydrate acetates

The adrenaline test for enzymes is a general back-titration procedure to detect 1,2-diols, 1,2-aminoalcohols and α-hydroxyketones reaction products of enzyme catalysis by colorimetry. The method was used to profile a series of esterases and lipases for their esterolytic activity on a series of carbohydrate and polyol acetates. Substrates were prepared by peracetylation and used for parallel microtiter-plate analysis of enzyme activities. This method can be used to achieve a rapid and automated characterization of a set of enzymes during HTS screening.

Acetoxy lactonization of alkenyl acetic acids promoted by ammonium persulfate and trifluoromethanesulfonic acid in acetic acid

The reactions of substituted 4-pentenoic and 3-butenoic acids with ammonium persulfate in acetic acid, in the presence of trifluoromethanesulfonic acid, gave the products of acetoxy lactonization in good yield.
