Abstract

This paper describes the preparation of some mercaptoisopentanols: 2-mercapto-3-methyl-1-butanol (I), 1-mercapto-3-methyl-2-butanol (II), 3-mercapto-3-methyl-2-butanol (III) and the unsaturated analogue of compound I - 2-mercapto-3-methyl-2-buten-1-ol (IV). These compounds belong to the flavonoid group present in food responsible for deterioration of their gustatory properties.
