摘要:The invention provides a process for the production of optically active propargyl alcohol useful as an intermediate in the synthesis of drugs. According to the invention, optically active propargyl alcohol is produced by asymmetric reduction of propargyl ketone with a secondary alcohol dehydrogenase or a carbonyl reductase.

摘要:The present invention provides a novel secondary alcohol dehydrogenase useful for the synthesis of optically active alcohol and DNA encoding said enzyme. A microorganism belonging to genus Candida was found to produce a novel secondary alcohol dehydrogenase with a high stereochemical specificity. Using said enzyme, optically active alcohols were prepared, and by cloning of DNA encoding said enzyme, the base sequence of said DNA was determined. By providing a novel secondary alcohol dehydrogenase with a high stereochemical specificity and the gene encoding said enzyme, an efficient production of optically active alcohols became possible.

摘要:Disclosed is a composition, a method of making and a method of using critical clusters for asymmetric synthesis using substantially optically-pure chiral solvent molecules in a supercritical fluid. The solvent molecules are capable of forming a multipoint hydrogen bonded solvate as they encage at least one solute molecule. The encaged solute molecule is capable of reacting to form an optically active chiral center. In another aspect, there is disclosed a method of directing the position of bonding between a solute molecule and a ligand involving encaging the solute molecule and the ligand with polar solvent molecules in a supercritical fluid under conditions of temperature and pressure sufficient to change electric charge distribution in the solute molecule. In yet another aspect, disclosed is a method of making pharmaceutical compounds involving encaging a solute molecule, which is capable of forming a chiral center, and a ligand with polar solvent molecules in a supercritical fluid under conditions of temperature and pressure sufficient to change electric charge distribution of the solute molecule. The solute molecule and ligand are then reacted whereby the ligand bonds to the solute molecule forming a chiral center. Also disclosed is a method for racemic resolution using critical clusters involving encaging racemic mixtures of solute molecules with substantially optically-pure chiral solvent molecules in a supercritical fluid under conditions of temperature and pressure sufficient to form critical clusters. The solvent molecules are capable of multipoint hydrogen bonding with the solute molecules. The encaged solute molecules are then nonenzymatically reacted to enhance the optical purity of the solute molecules.
