Marine Pyrrole Alkaloids [PDF]
Nitrogen heterocycles are essential parts of the chemical machinery of life and often reveal intriguing structures. They are not only widespread in terrestrial habitats but can also frequently be found as natural products in the marine environment. This review highlights the important class of marine pyrrole alkaloids, well-known for their diverse ...

Chemistry – An Asian Journal, 2015
AbstractThe dearomatization of heterocycles has been a powerful means for producing functional molecules in synthesis. In the case of pyrroles, reductive methods (such as the Birch reduction) have been most widely exploited, while oxidative methods are generally dismissed as too difficult or unpredictable to be useful.

The System Pyridine-Pyrrole and the Association of Pyrrole
The Journal of Chemical Physics, 1955Pyridine and pyrrole react together to form a 1:1 complex as shown by infrared, heat of reaction, viscosity, refractive index, and density data. The heat of formation of this complex is 3.8 kcal/mole. Pyrrole itself is associated, but, like the simple alcohols, cannot be represented by a simple equilibrium.

The Synthesis of 3-Substituted Pyrroles from Pyrrole
Synthesis, 1985La reaction d'electrophiles avec le pyrrole se fait preferentiellement en position 1 ou 2; pour obtenir des derives substitues en 3, on protege d'abord la position 1 ou 2 par des substituants orientant la reaction en position 3 ou on utilise en position 2 des substituants permettant un rearrangement conduisant aux pyrroles substituees en 3; une etape ...
