A scalable synthesis of chiral Vedejs-type DMAP catalysts is reported. The key step of the synthesis is amination of the enantiomerically pure 4-chloropyridine derivative using well-defined ZnCl2(amine)2 complexes. A series of Zn(II)-amine complexes have been synthesized to explore the scope of the ZnCl2-mediated amination of 4-halopyridines. Mechanistic studies support a Zn(II)-facilitated nucleophilic aromatic substitution as a plausible mechanism for the chlorine-to-amine exchange.

Individual molecular H complex of isosteviol with aniline (2:1) was isolated. The aniline NH2 group plays the role of proton donor and the isosteviol carboxy group, acts as proton acceptor. Isosteviol molecules bound to aniline molecules form double helices about the 43 chiral axis. In their turn, these helices are bound to each other by hydrogen bonds between isosteviol molecules of neighboring helices, thus forming a supramolecular crystal structure of the complex. The enthalpies of formation of the hydrogen bonds in the complex were estimated. In CCl4 solutions the complexes are in equilibrium with acid isosteviol dimers, their associates with aniline, as well as free isosteviol and aniline molecules.
