Structurally diverse pyridinium salts are quite familiar structures in many natural products
and bioactive pharmaceuticals. Over the centuries, these privileged scaffolds have played …

The present review focuses on strategies for the construction of piperidines which have
appeared in the literature since 2003 through mid-2017. In a preceding chapter …

The N-(2-pyridyl)-N′-ethylpiperazines are important structural motifs in several medicinally
relevant compounds. Known synthetic methods toward these structures are multistep and …

An unprecedented C2‐alkylation of quinoline N‐oxide derivatives via C− C bond activation
of tert‐and sec‐alkyl alcohol is described using hypervalent iodine (III) reagent PhI (OAc) 2 …

A visible‐light‐induced site selective C− H alkylation of heterocyclic N‐oxides with N‐
hydroxyphthalimide esters was developed using Eosin Y as the photocatalyst in the …

A study of saturated vapor over the pyridine N-oxide-boron trifluoride (PyO-BF3) adduct was
carried out at T= 448 (5) K by a synchronous gas electron diffraction/mass spectrometry …

The particular nature of tetrahydropyrido [4, 3-e]-1, 4, 2-dioxazines of type 1 allows the regio-
and stereoselective obtainment of substituted N-carbamoyl tetrahydropyridines by common …

Organomagnesium reagents are among the most important reagents in organic chemistry
because of their great utility in forming carbon–carbon bonds. Although most …

A transition-metal-free intramolecular cross dehydrogenation coupling reaction of pyridinium
was developed. The C (sp2)–H/C (sp2)–H coupling reaction involved an unprecedented …

The pyridine scaffold is present in a number of natural products, biologically active materials,
as well as in materials with interesting physical–chemical properties. As such, their …
