标 题 :Synthesis of enantiomerically pure amino-substituted fused bicyclic rings
发明人：MCEACHERN ERNEST J; BRIDGER GARY J; SKUPINSKA KRYSTYNA A; SKERLJ RENATO T; YANG WEN
权利人:ANORMED INC
摘要:This invention describes various processes for synthesis and resolution of racemic amino-substituted fused bicyclic ring systems. One process utilizes selective hydrogenation of an amino-substituted fused bicyclic aromatic ring system. An alternative process prepares the racemic amino-substituted fused bicyclic ring system via nitrosation. In addition, the present invention describes the enzymatic resolution of a racemic mixture to produce the (R)- and (S)-forms of amino-substituted fused bicyclic rings as well as a racemization process to recycle the unpreferred enantioner. Further provided by this invention is an asymmetric synthesis of the (R)- or (S)-enantiomer of primary amino-substituted fused bicyclic ring systems.

标题 :Process for synthesis of alpha, beta-unsaturated ketones
发明人：PATEL IAN; HOPES PHILIP
权利人:ASTRAZENECA AB
摘要:A method for the synthesis of an α,β-unsaturated ketone useful for making substituted 1,4-dihydropyridines is described by reacting an aldehyde with pyrrolidine and then adding a ketone followed by trifluoroacetic acid at low temperature. The synthesis is used in a process for making substituted 1,4-dihydropyridines wherein a vinylogous amide is prepared by reacting a 1,3-cyclohexanedione with a phenylethylamine. The α,β-unsaturated ketone can be reacted with a vinylogous amide to form a 1,5-diketone which can be converted to a substituted 1,4-dihydropyridine.
