专利号:US-6841559-B1 优先权日:1999-11-19 标 题:Pyridinones to treat and prevent bacterial infections 发明人:ALMQVIST FREDERIC; EMTENAS HANS; HULTGREN SCOTT J; PINKNER JEROME S 权利人:WASHINGTON UNIVERSITY OF ST LO 摘要:Novel pyridinones and their derivatives which are effective in treating or preventing Gram-negative bacterial infections are provided. The pyridinones are stable and easily derivatized; the methods by which these derivatizations occur is described. Two regioselective and functional group tolerant methods for the synthesis of the novel pyridinones are also provided. One such synthetic method involves reacting an imine and a Meldrum's acid derivative in solution. The other synthetic method is a solid phase synthesis of the pyridinones in which an imine is prepared bound to a solid support and a Meldrum's acid derivative is reacted with the imine. Novel imine intermediates useful in the solid phase and solution methods of synthesizing the pyridionones are also described.

专利号:US-11981653-B2 优先权日:2021-07-10 标 题:Synthesis method of chiral (S)-nicotine 发明人:ZOU JUN; ZOU YANG; LIU MEISEN; LUO WEIXIAN 权利人:SHENZHEN ZINWI BIO TECH CO LTD 摘要:The present application discloses a synthesis method of chiral nicotine from nicotinate and γ-butyrolactone, including the following steps: Step S1: performing condensation under an alkaline condition, and performing ring opening reaction with hydrochloric acid; Step S2: reacting with (+)—B-diisopinocampheyl chloroborane to produce a chiral hydroxyl group; Step S3: performing a chlorination reaction; and Step S4: performing cyclization under an alkaline condition to obtain the chiral nicotine. In the present application, nicotinate and γ-butyrolactone, both cheap and readily available, are used as raw materials, so as to reduce the production cost of (S)-nicotine. (+)—B-diisopinocampheyl chloroborane is used to reduce a carbonyl group of an intermediate to obtain a target chiral center. The (+)—B-diisopinocampheyl chloroborane induces the production of a chiral hydroxyl group, chlorination and cyclization are performed to form chiral (S)-demethylnicotine, and finally amine methylation is performed to obtain (S)-nicotine with photochemical activity.
