The process is particularly suitable for the synthesis of ureas and of their polymers.
专利号:US-5329022-A 优先权日:1991-01-16 标 题:Process for the synthesis of citraconimides 发明人:TALMA AUKE G; HOOFT HENDRIKA P M; VAN DE BOVENKAMP-BOUWMAN ANNA 权利人:AKZO AMERICA INC 摘要:The present invention relates to an improved synthesis method for the making of citraconimides wherein a citraconic anhydride is reacted with 0.5 to 2.0 equivalents of at least one amine salt. This process may be carried out in a solvent and generally leads to excellent yields of the citraconimides with high selectivity and easy purification. The present inventional so relates to a process for the production of citraconic anhydride from itaconic anhydride with an amine or phosphine catalyst and in a cosolvent.

专利号:US-2009111737-A1 优先权日:1999-05-24 标题:Novel antibacterial agents 发明人:CHRISTENSEN BURTON G; MORAN EDMUND J; GRIFFIN JOHN H; JUDICE J KEVIN; MU YONGQI; PACE JOHN L; MAMMEN MATHAI; AGGEN JAMES 权利人:CHRISTENSEN BURTON G; MORAN EDMUND J; GRIFFIN JOHN H; JUDICE J KEVIN; MU YONGQI; PACE JOHN L; MAMMEN MATHAI; AGGEN JAMES 摘要:This invention relates to novel multibinding compounds (agents) that are antibacterial agents. The multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands in their monovalent (i.e., unlinked) state have the ability to bind to a an enzyme involved in cell wall biosynthesis and metabolism, a precursor used in the synthesis of the bacterial cell wall and/or the bacterial cell surface thereby interfere with the synthesis and/or metabolism of the cell wall. In particular the multibinding compounds of the invention comprise from 2-10 ligands covalently connected by a linker or linkers, wherein each of said ligands hasn a ligand domain capable of binding to penicillin binding proteins, a transpeptidase enzyme, a substrate of a transpeptidase enzyme, a beta-lactamase enzyme, pencillinase enzyme, cephalosporinase enzyme, a transglycoslase enzyme, or a transglycosylase enzyme substrate; Preferably, the ligands are selected from the beta lactam or glycopeptide class of antibacterial agents.
