Nitrogen heterocycles as potential monoamine oxidase inhibitors: Synthetic aspects
Arabian Journal of Chemistry, 2014 The present review highlights the synthetic methods of monoamine oxidase inhibitors (MAO) belonging to a group of nitrogen heterocycles such as pyrazoline, indole, xanthine, oxadiazole, benzimidazole, pyrrole, quinoxaline, thiazole and other related ...

Isocyanides in the Synthesis of Nitrogen Heterocycles
Angewandte Chemie International Edition, 2010AbstractIsocyanides have long proved themselves to be irreplaceable building blocks in modern organic chemistry. The unique features of the isocyano group make isocyanides particularly useful for the synthesis of a number of important classes of nitrogen heterocycles, such as pyrroles, indoles, and quinolines.

Photooxygenations of nitrogen heterocycles
Chemical Reviews, 1979This review attempts to catalogue some of the reported photooxygenated reactions of different nitrogen heterocycles. Attention has been focused on the different types of products formed in these reactions and some of the suggested pathways for their formation. Although detailed studies on the mechanism of photooxygenation reactions have been performed,

N‐Atom Deletion in Nitrogen Heterocycles
Angewandte Chemie International Edition, 2021AbstractExcising the nitrogen in secondary amines, and coupling the two residual fragments is a skeletal editing strategy that can be used to construct molecules with new skeletons, but which has been largely unexplored. Here we report a versatile method of N‐atom excision from N‐heterocycles.

Many advantages accrue from nitrogen-rich heterocyclic compounds compared to traditional molecular energetic compounds. Utilization of heterocyclic nitrogen-containing cations and anions in energetic salts gives rise to lower vapor pressures, higher heats of formation and higher densities. Additionally, smaller amounts of hydrogen and carbon contribute
