    摘要:
    Three new routes to derivatives of alpha-fluoracrylic acid, including a laboratory synthesis and a large-scale method, are reported. The processes are (i) addition of elementary fluorine to acrylic esters and subsequent elimination of HF; (ii) addition of difluorocarbene to isopropenyl methyl ether, oxidation via ring opening and dehalogenation; and (iii) 'nitrofluorination' of 2,3-dichloropropene, hydrolysis and dechlorination.

  • Inhibition of human leukocyte elastase by functionalized N-aryl azetidin-2-ones: substituent effects at C-3 and benzylic positions
    作者:I Vergely、N Boggetto、V Okochi、S Golpayegani、M Reboud-Ravaux、R Kobaiter、R Joyeau、M Wakselman
    DOI:10.1016/0223-5234(96)88226-2
    日期:1995.1
    A series of functionalized N-aryl azetidin-2-ones with a latent alkylating group was prepared by a flexible four-step synthesis. They met criteria expected for a suicide-type inactivation of human leukocyte elastase (HLE) and porcine pancreatic elastase (PPE), with no inactivation of trypsin- and chymotrypsin-like proteases. The inhibition potency was dependent on the halogen substituents at C-3 (F, F; Cl, Cl; Br, Br) and the nature and the position relative to nitrogen of the latent benzylic leaving group (F, Cl, Br). Better inactivations of HLE compared with PPE were observed with azetidinones gem-disubstituted by Cl and Br rather than by F. Their protio analogs, which are devoid of the latent quinoniminium methide electrophile, behave as simple substrates of elastases.

  • N-Aryl 3-halogenated azetidin-2-ones and benzocarbacephems, inhibitors of .beta.-lactamases
    作者:Roger Joyeau、Huguette Molines、Roger Labia、Michel Wakselman
    DOI:10.1021/jm00397a018
    日期:1988.2
    N-(3-Carboxy-6-methylphenyl)-3-fluoroazetidin-2-one and a series of related N-aryl-3-halo- and -3,3-dihaloazetidinones 3, in which the halo substituent is a fluorine or a bromine atom, were prepared by using the Wasserman procedure of cyclization of beta-bromopropionamides as a key step. Their affinities for the TEM-1 beta-lactamase were determined and compared with those of a series of tricyclic azetidinones
