Abstract: Optically active organic compounds are prepared starting from optically inactive reactants by means of an optically active agent which influences the course of the reaction. In particular optically active compounds having a "meso" type carbon atom undergo an intramolecular ring closure in the presence of an optically active agent to yield an optically active product having one additional ring. The present process is particularly useful in the preparation of optically active bicyclic diketones which are important intermediates in the total synthesis of steroids.

Abstract: A process for the production of isophorone involving side-stream removal of a fraction in which color forming compounds are concentrated and treatment thereof with a strong mineral acid to decompose the contaminants into higher boiling compounds. Additionally the bulk of the isophorone is separated from the aqueous phase in the presence of a strong acid which serves to neutralize the alkali catalyst. Such treatment aids phase separation and minimizes beta-isophorone production. Alpha-isophorone is recovered from both fractions.
