Abstract:
A ruthenium-catalyzed [2+2+2] cycloaddition between α,ω-diynes and cyanamides is reported under microwave irradiation to access 2-aminopyridines. In contrast to the classical thermal conditions, this atom-economical sustainable protocol allows access to diverse functionalized 2-aminopyridine derivatives with high yields and excellent regioselectivities in MeTHF with short reaction times.

Abstract:
Unsubstituted pyridin-2-amine has a high quantum yield and is a potential scaffold for a fluorescent probe. However, the facile access to conjugated highly substituted aminopyridines and the study of their fluorescent properties is scarce. In this paper, synthesis and fluorescent properties of multisubstituted aminopyridines were studied based on a recently developed Rh-catalyzed coupling of vinyl azide with isonitrile to form a vinyl carbodiimide intermediate, following tandem cyclization with an alkyne. An aminopyridine substituted with an azide group as a potential probe was further designe

Abstract:
2-aminopyridines scaffolds are an important class of nitrogen heterocyclic compounds with a wide range of biological activities. Multicomponent reactions (MCRs) are useful methods for the construction of nitrogen heterocyclic compounds. In this context, syntheses of 2-aminopyridines derivatives via MCRs have attracted considerable attention in recent years. We present, in this work, a rapid and efficient synthesis of 2-aminopyridine derivatives, via the catalyst-free four-component method. This protocol provides a simple and practical approach to functionalized 2-aminopyridnes from readily ava

Abstract:
A short and economical synthesis of various 2-methylaminopyidine amides (MAPA) from 2-bromopyridine has been developed using the catalytic Goldberg reaction. The effective catalyst was formed in situ by the reaction of CuI and 1,10-phenanthroline in a 1/1 ratio with a final loading of 0.5–3 mol%. The process affords high yields and can accommodate multigram-scale reactions. A modification of this method provides a new preparation of 2-N-substituted aminopyridines from various secondary N-alkyl(aryl)formamides and 2-bromopyridine. The intermediate aminopyridine formamide is cleaved in situ thro

Abstract:
AbstractA synthesis of 2-aminopyridines from pyridine N-oxides via their corresponding N-(2-pyridyl)pyridinium salts has been demonstrated and investigated. The reaction sequence features a highly regioselective conversion of the N-oxide into its pyridinium salt followed by hydrolytic decomposition of the pyridinium moiety to furnish the 2-aminopyridine product. The method is compatible with a wide range of functional groups, is scalable, and features inexpensive reagents. 15N-labeling results gave products consistent with a Zincke reaction mechanism.
