标 题 :Process of preparing enriched enantiomers of glycerol carbonate and derivatives thereof for synthesis of β-blockers
发明人：OLIVERO ALAN G; CASSEL JONATHAN M; POULSEN JAMES R
权利人:COGNIS INC
摘要:Enriched enantiomers of glycerol Carbonate are produced under the influence of a hydrolytic enzyme, either by selective esterification of racemic glycerol carbonate or by selective hydrolysis of an ester of the racemate. The enriched enantiomeric product is readily converted to starting materials and intermediates useful in the synthesis of enantiomerically pure therapeutic agents, such as beta -adrenergic blockers.

标题:Synthesis of compounds with predetermined chirality
发明人：MYERS ANDREW G
权利人:CALIFORNIA INST OF TECHN
摘要:A method for synthesizing enantiomerically enriched chemical intermediates with predetermined chirality is described. The method comprises formation of a pseudoephedrine amide, followed by stereoselective alkylation at the alpha carbon. The chiral auxiliary can then be cleaved off, affording chiral end products useful for further transformations. The enantiomeric enrichment of the chiral end products may exceed 98%, and the chiral auxiliary can be recovered. Novel amides of pseudoephedrine used in this method are also disclosed.
