Simultaneous derivatization of acyl and S-alkyl moieties of acyl thioesters by using trimethylsulfonium hydroxide for gas chromatographic analysis.

E Klein1, N Weber.   

Abstract

The reaction of long-chain acyl thioesters, viz. lauric acid dodecyl thioester, 1,8-di-S-palmitoyl octanedithiol, and tristearoyl alpha-monothioglycerol, with trimethylsulfonium hydroxide in the presence of methanol leads to simultaneous derivatization of acyl moieties and S-alkyl moieties of acyl thioesters to the corresponding fatty acid methyl esters and methyl alkylsulfides, respectively. These derivatized products were analyzed by gas chromatographic technique.
