Nitrogen-fused Heterocycles: Empowering Anticancer Drug Discovery.
Medicinal chemistryThe worldwide impact of cancer is further compounded by the constraints of current anticancer medications, which frequently exhibit a lack of selectivity, raise safety apprehensions, result in significant adverse reactions, and encounter resistance ...

Recent advances in biocatalysis of nitrogen-containing heterocycles.
Biotechnology Advances, 2021Nitrogen-containing heterocycles (N-heterocycles) are ubiquitous in both organisms and pharmaceutical products. Biocatalysts are providing green approaches for synthesizing various N-heterocycles under mild reaction conditions. This review summarizes the

Journal of coordination chemistry, 2019
The review is a follow-up of a previous article (I. Haiduc, J. Coord. Chem. (2019). DOI: 10.1080/00958972.2019.1641702), which introduced structures with five-membered nitrogen heterocycles as inverse coordination centers. This review presents a panorama

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,

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

Synthesis of Five-Membered Iodine-Nitrogen Heterocycles from Benzimidazole-Based Iodonium Salts.
Journal of Organic Chemistry, 2018Pseudocyclic 2-benzimidazolyl-substituted diaryliodonium salts were obtained by the reaction of the corresponding [hydroxy(tosyloxy)iodo]arenes with arenes in the presence of trifluoromethanesulfonic acid.
