Abstract:

Due to frequent occurrence of nitrogen-containing groups among the biologically active compounds, chemoselective functionalization of organic molecules with nitrogen-containing functional groups is an important area of organic synthesis. We have proposed and implemented a new strategy toward design of nitrogen-transfer reactions on inert electrode surfaces with a particular focus on the generation and trapping of highly reactive nitrogen-transfer agents. A wide range of structurally dissimilar olefins can be readily transformed into the corresponding aziridines. The resulting aziridines are pr

Abstract:

The synthesis and structure of nitrogen-containing heterocycles are fascinating because these compounds have a great richness of structural, physicochemical, and biological properties. Therefore, the development of improved ways for the synthesis of polyfunctional nitrogen-containing heterocycles continues to be a challenging goal. This account describes developments in the discovery of C–H/N–H bond functionalization and oxidative cyclization procedures for the synthesis of nitrogen-containing heterocycles (aziridines, indoles, indolizines, triazoles, imidazoles, oxazoles, thiazoles, quinoxali

Abstract:

Heterocyclic compounds containing nitrogen ions, like pyrazoles, aziridines, diaziridines and their metal ion complexes with Cu(II), Zn(II) and Ru(III) and others exhibit a wide range of biological activity, including mainly anti-inflammatory, antioxidant, anticancer, and antimicrobial properties. Biological significance of these molecules and thus their potential use in medicine has driven growing interest into their coordination chemistry. A knowledge of the relationship between the structure of chemical compounds and their activity is needed for the synthesis of the preparations possessing

Abstract:

β-Lactams represent flexible building blocks suitable for the preparation of a large variety of nitrogen-containing target compounds. In the present study, the formerly neglected synthetic potential of 4-haloalkyl-β-lactams has been elaborated in detail with a focus on the preparation of different mono- and bicyclic heterocycles. A first approach involved ring transformations of these halogenated building blocks toward stereodefined aziridines, azetidines, pyrrolidines, and piperidines via intermediate aziridinium or azetidinium ions. In a second part, novel and stereoselective entries into 1,

Abstract:

Peptidomimetics containing an aziridine moiety have been reported as potent cysteine protease inhibitors. In this sense, the development of stereoselective and sustainable synthetic strategies to obtain three-membered N-heterocyclic compounds has gained importance in the last decades. In this work, an efficient method was designed to achieve highly functionalized aziridine peptidomimetics via a sequential reaction, which involves the organocatalytic aziridination of α,β-unsaturated aldehydes followed by the Passerini multicomponent reaction in an environmentally friendly solvent mixture (ethan

Abstract:

Amide derivatives of 2-allylanilines have been prepared by metallation of the amide derivatives of the corresponding 2-bromoanilines and subsequent reaction with an allylic halide. The electrophile -promoted cyclization of these compounds has been investigated. The free allylanilines readily undergo aminomercuration to form unstable mercury derivatives of tetrahydroquinolines but the corresponding amide derivatives do not cyclize. Instead, oxymercuration of the double bond occurs. The allylanilines react with iodine to yield 3-iodo-1,2,3,4-tetrahydroquinolines. The anion of 2,2,2-trifluoro-N-[
