Part 1. the mesomorphic properties of arloxy-s-triazines and their analogs, Part 2. the synthesis and polymerization behavior of α-aminonitriles and related compounds
… with these compounds in the mesophase. Part 2. α-Aminonitriles and their derivatives have played an important role in the synthesis of enantiomerically pure and racemic α-amino acids for almost ninety years. Much less studied is the alkylation behavior of this particular class of compounds. The …

Methoden zur asymmetrischen nucleophilen Glyoxylierung
… the application of chiral and racemic glyoxylate aminonitriles in developing both a stoichiometric as an organocatalytic procedure for the synthesis of beta-substituted alpha-ketoesters. This could be realised by applying the concept of Umpolung, which enables the nucleophilic introduction of the …

Zur asymmetrischen Synthese von Beta-Thio-Alpha-Aminosäuren
… cleavage with SmI2 resulted the protected aminonitriles. Unhappily, no method could be found to transform the nitriles into the correspondending amino acids neither under acidic nor under basic conditions. Only decomposition can be observed. Nevertheless, the sulfidic group of the …

Part I: Synthesis of Aromatic Polyketones Via Soluble Precursors Derived from Bis(A-Amininitrile)S; Part Ii: Modifications of Epoxy Resins with Functional Hyperbranched Poly(Arylene Ester)s
… DMF yielded soluble, high molecular weight polyaminonitriles, which were hydrolyzed in acidic conditions to produce the corresponding polyketones. A novel approach to the synthesis of high molecular weight wholly aromatic polyketones without ether linkages or alkyl substituents in the polymeric …
