This review examines the use of baker's yeast as a reagent in organic synthesis, with an emphasis on the developments of the last 15 years. The transformations of various classes of compounds are examined, for example, reduction or formation of double bonds, acyloin condensation. The equivalent microbial transformations are compared in relevant cases. 1. Introduction 2. Reduction of β-Keto Esters 3. Reduction of other Keto Acid Derivatives 4.
