ON PYRIDINE HEMOCHROMOGEN [PDF]
Journal of General Physiology, 1929 1. Cyanide hemochromogen probably contains one cyanide group per heme group. 2. The equilibrium between pyridine hemochromogen and its components, pyridine and reduced heme, is complicated to an unknown extent by the precipitation of reduced heme and the aggregation of pyridine hemochromogen. 3.

An Efficient Synthesis of Novel Pyrazole-Based Heterocycles as Potential Antitumor Agents
Applied Sciences, 2017 A new series of pyrazolylpyridines was prepared by reaction of ethyl-3-acetyl-1,5-diphenyl-1H-pyrazole-4-carboxylate with the appropriate aldehyde, malononitrile, or ethyl acetoacetate and an excess of ammonium acetate under reflux in acetic acid ...

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 ...
