A micromethod for identification of hydroxy acids

Analytical Biochemistry, 1968
Abstract A micromethod for the identification of hydroxy acids is described. The method depends on converting the hydroxy acid to the corresponding bromo acid with phosphorus tribromide and then dehydrobrominating the bromo acid with potassium tert -butoxide in tert -butyl alcohol.

A convenient preparative method of 3‐hydroxy acids, and the reaction of 3‐hydroxy acids with acidic materials

Journal of Applied Chemistry and Biotechnology, 1977
Abstract3‐Hydroxy acids were synthesised in good yield from ketones and carboxylic acids using lithium naphthalenide in the presence of diethylamine. From cyclohexanone and propionic acid, 2‐(1′‐hydroxycyclohexan‐1′‐yl) propionic acid (I) was obtained in 98.3% yield.
