A novel catalyst-free synthesis ofN-pyridin-2-yl,N-quinolin-2-yl, andN-isoquinolin-1-yl carbamates utilizes easily accessibleN-hetaryl ureas and alcohols. The proposed environmentally friendly technique is suitable for the good-to-high yielding synthesis of a wide range ofN-pyridin-2-yl orN-quinolin-2-yl substituted carbamates featuring electron-donating and electron-withdrawing groups in the azine rings and containing various primary, secondary, and even tertiary alkyl substituents at the oxygen atom (48-94%; 31 examples). The DFT calculation and experimental study showed that the reaction proceeds through the intermediate formation of hetaryl isocyanates. The method can be applied to obtainN-isoquinolin-1-yl carbamates, although in lower yields, and ethyl benzo[h]quinolin-2-yl carbamate has also been successfully synthesized (68%).

A series of substituted 2-aminopyridines was prepared and evaluated as inhibitors of human nitric oxide synthases (NOS). 4,6-Disubstitution enhanced both potency and specificity for the inducible NOS with the most potent compound having an IC50 of 28 nM.

A variety of novel chelating 1,3-bis(2'-pyridylimino)isoindoline ligands were prepared and characterized including ligands substituted on both the pyridyl and isoindoline ring systems.Noteworthy are the first isoindoline ligands with solubility in aqueous media.A convenient preparation of 4-alkoxyphthalonitriles is reported; these compounds are readily obtained from 4-nitrophthalonitrile and are suitable starting materials for alkoxy-substituted ligands.
