Vilches-Herrera, Marcelo,Werkmeister, Svenja,Junge, Kathrin,Boerner, Armin,Beller, Matthias
, p. 629 - 632 (2014/03/21)
The catalytic transfer hydrogenation of (hetero)aryl nitriles using ammonium formate has been investigated in detail. In the presence of commercially available Pd/C, a straightforward and selective reduction is achieved without any additives under mild conditions.

-
Page/Page column 47-48, (2012/06/01)
A method of enhancing binding of cells to an integrin-binding ligand comprises treating integrin-expressing cells in vitro with an agonist of integrin, wherein the integrin is selected from the group consisting of α4β1, α5β1, α4β7, αvβ3 and αLβ2, and contacting the treated cells with an integrin-binding ligand; integrin agonist compounds having the general formula I; methods of treating integrin-expressing cells with such agonists to enhance binding; and therapeutic methods comprising administering agonist-treated cells or agonist compounds to a mammal.

Addis, Daniele,Enthaler, Stephan,Junge, Kathrin,Wendt, Bianca,Beller, Matthias
experimental part, p. 3654 - 3656 (2009/10/04)
Easily accessible in situ catalysts composed of [Ru(cod)(2-methylallyl)2] and N-heterocyclic carbene ligands have been developed for the environmentally benign hydrogenation of various nitriles to give primary amines. Applying optimized conditions in the presence of SIMesBF4 as ligand high catalyst activity of up to 392 h-1 is achieved in the hydrogenation of benzonitrile. The general applicability and functional group tolerance of this novel catalyst system are shown in the reduction of ten different nitriles.

Enthaler, Stephan,Addis, Daniele,Junge, Kathrin,Erre, Giulia,Beller, Matthias
experimental part, p. 9491 - 9494 (2009/10/14)
An easily accessible in situ catalyst composed of [Ru(cod)methylallyl 2] and DPPF was developed for the environmentally benign hydrogenation of various nitriles to give primary amines. A solution of benzonitrile in toluene was transferred by syringe into an autoclave that contained argon and KOtBu. The catalyst was generated in situ by stirring [Ru(cod)methylallyl2] and DPPF in toluene for 10 min and transferring the solution by syringe into the autoclave. the reaction mixture was filtered through a short plug of silica gel and the yield was measured by GC. A superior catalyst activity with a TOF of up to 5783 h-1 is achieved in the model reaction under optimized conditions. The results also show that [Ru(cod)methylallyl2]/DPPF catalyst system exhibit a broad functional group tolerance.

Page column 18, (2010/11/30)
This application relates to a piperazino-substituted novel cyanophenyl derivative in which a substituted carbamoyl or substituted sulfamoyl group having an aryl, heterocyclic or the like group that may have a substituent group is bonded to one nitrogen atom on the piperazine ring. The compound of this application has an anti-androgen action and is useful in preventing or treating prostatic cancer, benign prostatic hyperplasia and the like diseases.
Synthesis and herbicidal activity of 2-cyano-3-substituted-pyridinemethylaminoacrylates
Wang, Qingmin,Sun, Huikai,Cao, Huanyan,Cheng, Muru,Huang, Runqiu
, p. 5030 - 5035 (2007/10/03)
Two series of 2-cyano-3-substituted-pyridinemethylaminoacrylates, namely 12 new (Z)-2-cyano-3-methylthio-3-substituted-pyridinemethaneaminoacrylates and 10 new (Z)-2-cyano-3-alkyl-3-substituted-pyridinemethaneaminoacrylates, were synthesized as herbicidal inhibitors of photosystem II (PSII) electron transport. All of these compounds were confirmed by 1H NMR, elemental, IR, and mass spectrum analyses. Their herbicidal activities were evaluated. Some compounds exhibited excellent herbicidal activities, even at a dose of 75 g/ha. A suitable substituent at the 2-position of the pyridine ring and the well-fit group at the 3-position of acrylate were essential for high herbicidal activity. 2-Cyanoacrylates containing a substituted pyridine ring provide higher herbicidal activities than parent compounds containing phenyl. These PSII inhibitor herbicides are safe to corn, which is a major crop in China.
