Scope and Limitations of a Novel Synthesis of 3-Arylazonicotinates
Molecules, 2012 The reaction of 3-oxo-3-phenyl-2-phenylhydrazonal with functionally substituted and heteroaromatic substituted acetonitrile to yield arylazonicotinic acid derivatives and 5-arylsubstituted pyridines was established. In some cases the produced nicotinates

Metastable Transitions in Pyridine and Pyridine Derivatives [PDF]
Zeitschrift für Naturforschung A, 1981 The kinetic energy released in metastable transitions in pyridine, 2, 3, 4 acetylpyridine and 2, 3, 4 aminopyridine differs for the different isomers. This indicates that the dissociation path-way of these compounds depends on the position of the nitrogen atom in the isomer.

From Pyridine to (−)‐Agelastatin A
Advanced Synthesis & Catalysis, 2023 Abstract(−)‐Agelastatin A was synthetized employing a flow photorearrangement of a pyridinium salt, constructing in one step the cyclopentene core possessing the desired functionalities and relative configurations. A flow enzymatic kinetic resolution of the resulting bicyclic vinyl aziridine delivered the enantiopure precursor to the natural product ...
