专利号:US-5569762-A 优先权日:1994-01-14 标题:Asymmetric synthesis of intermediates for retroviral protease inhibitor compounds 发明人:WISSNER ALLAN; TROVA MICHAEL P 权利人:AMERICAN CYANAMID CO 摘要:The disclosure describes an improved process for producing optically active compounds of Formula II or III, which compounds are useful as intermediates for preparing compounds active as inhibitors of retroviral protease enzymes: ##STR1## wherein R 1 , R 50 and Z are described in the specification. The improved process includes either synthesis of diastereomeric iodolactones which are separated prior to conversion to compounds of Formula II or III or synthesis of an epoxide which is converted directly to compounds of Formula II and III.
专利号:US-4914220-A 优先权日:1988-05-23 标题 :Process for synthesis of E-2-methyl-α,β-unsaturated aldehydes 发明人:DESMOND RICHARD; MILLS SANDER G; VOLANTE RALPH P; SHINKAI ICHIRO 权利人:MERCK & CO INC 摘要:A process is described for the synthesis of E-2-methyl-α,β-unsaturated aldehydes, which are useful as intermediates in the synthesis of the macrolide structure of the immunosuppressant FK-506. These compounds are also useful as ultraviolet radiation absorbers.
专利号:US-6995289-B2 优先权日:2000-08-02 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.
