标题 :Process for the preparation of polymers of dimeric cyclic esters
发明人：BAKER GREGORY L; SMITH III MILTON R
权利人:UNIV MICHIGAN STATE
摘要:The present invention provides a process for the direct synthesis of high melting polymers made from dimeric cyclic esters. In particular, the present invention provides a process for synthesis of polylactic acid (PLA) from racemic materials such as racemic lactide and polymandelide from mandelide. The process further provides racemic metal organic ligand catalysts such as racemic salbinap that catalyzes the polymerization of racemic dimeric cyclic ester monomers to a polylactide stereocomplex. Polymandelide and mixed dimeric cyclic esters are also prepared in the presence of low amounts of water.

摘要:The invention relates to methods for producing primary, secondary and tertiary amines and corresponding enantiopure or enantioenriched primary or secondary amine products, comprising the steps of reductively aminating a ketone, with a nitrogen auxiliary in the presence of a hydrogenating catalyst and a hydrogenating agent, wherein the reductive animation is performed under the influence of a mild Lewis acid, the mild Lewis acid being present at the onset of the reductive amination in at most 25 mol% of the ketone or the nitrogen auxiliary.

发明人：JACOBSEN ERIC N; TOKUNAGA MAKOTO; LARROW JAY F
权利人:HARVARD COLLEGE
摘要:The present invention relates to a process for stereoselective or regioselective chemical synthesis which generally comprises reacting a nucleophile and a chiral or prochiral cyclic substrate in the presence of a non-racemic, chiral catalyst to produce a stereoisomerically- and/or regioisomerically-enriched product. The present invention also relates to hydrolytic kinetic resolutions of racemic and diastereomeric mixtures of epoxides.
