Abstract
Enantiospecificity of the reduction process and product yields in the reduction of ethyl acetoacetate and ethyl benzoylacetate by baker's ye ast immobilized in calcium aliginate beads depend strongly on the pH o f the medium, and under optimum conditions products with high yields ( 80-85%) and high optical purity (e.e. 90-99%) can be obtained.
