The synthesis generally includes the preparation of an ester or an amide containing a leaving group followed by the formation of a salt.
专利号:US-4801744-A 优先权日:1985-03-01 标 题 :Catalytic synthesis of urea from carbon monoxide and amine compound 发明人:HERMAN JEAN-JACQUES; LECLOUX ANDRE 权利人:SOLVAY 摘要:Process for the catalytic synthesis of nitrogen-containing organic compounds, comprising the reaction of carbon monoxide with at least one amino compound in a reaction mixture containing a catalyst based on selenium and a substituted pyridine. The process is particularly suitable for the synthesis of ureas and of their polymers.
专利号:US-10913749-B2 优先权日:2015-05-07 标 题 :Macrocyclization reactions and intermediates and other fragments useful in the synthesis of halichondrin macrolides 发明人:FANG FRANCIS G; KIM DAE-SHIK; CHOI HYEONG-WOOK; CHASE CHARLES E 权利人:EISAI R&D MAN CO LTD 摘要:The invention provides methods for the synthesis of a halichondrin macrolides through a macrocyclization strategy. The macrocyclization strategy of the present invention involves subjecting a non-macrocyclic intermediate to a carbon-carbon bond-forming reaction (e.g., an olefination reaction (e.g., Horner-Wadsworth-Emmons olefination), catalytic Ring-Closing Olefin Metathesis, or Nozaki-Hiyama-Kishi reaction) to afford a macrocyclic macrolide. The invention also provides compounds useful as intermediates in the synthesis of a halichondrin macrolides and methods for preparing the same.
专利号:US-2025179020-A1 优先权日:2023-12-05 标 题:Synthesis of bis-oxime heterocycles 发明人:BLUMBERG SHAWN T; DORSEY CHRISTOPHER L 权利人:SOUTHWEST RES INST 摘要:A synthesis of bis-oxime heterocycles via reaction of 2,4-dimethyl pyridine or 2,4-dimethylpyrimidine in the presence of a phase transfer catalyst. Such bis-oxime heterocycles provide a more direct route to the synthesis of bis-quaternary pyridinium compounds and their analogs as nerve agent antidotes.
