Patent number: 4434106Abstract: Perfluoroether triazine elastomers having improved properties and utility in seals, gaskets, sealing components and the like are prepared from oligomeric imidoylamidines that have, in turn, been prepared by the process of (a) reacting a perfluorodinitrile with liquid ammonia to yield a perfluorodiamidine, (b) isolating the perfluorodiamidine, (c) reacting the isolated diamidine with a perfluorodinitrile to yield a perfluoro(imidoylamidine) dinitrile, and then repeating steps (a), (b), and (c) to sequentially grow an oligomer of desired molecular size. The isolated amidine and nitrile intermediates are also disclosed.Type: GrantFiled: April 6, 1982Date of Patent: February 28, 1984Assignee: The United States of America as represented by the Administrator of the National Aeronautics and Space AdministrationInventors: Robert W. Rosser, Timothy S. Chen, Chung-Heng Cheng

Patent number: RE46424Abstract: The present invention describes a method for the synthesis of enantiomerically pure 3-amidinophenylalanine derivatives, which are used as pharmaceutically effective urokinase inhibitors, by starting from 3-cyanophenylalanine derivatives. The methods of manufacture comprising only one synthesis step lead to new intermediates, namely 3-hydroxyamidino- and 3-amidrazonophenylalanine derivatives. These intermediates or their acetyl derivatives can be reduced into the desired 3-amidino-phenylalanine derivatives under gentle conditions (H2 or ammonium formiate formate, Pd/C (approx. 10%), ethanol/water, room temperature, normal pressure or also H2, Pd/C, AcOH or HCl/ethanol, 1-3 bar) in excellent yields and in an enantiomeric excess of up to 99.9%.Type: GrantFiled: December 31, 2013Date of Patent: June 6, 2017Assignee: Wilex AGInventors: Hugo Ziegler, Peter Wikstroem
