Preparation of vic-Mercaptoisopentanols.

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.
