An efficient and chemoselective synthesis of N-substituted 2-aminopyridines via a microwave-assisted multicomponent reaction.
A facile and selective synthesis of N-substituted 2-aminopyridines is accomplished via microwave-assisted multi-component reactions controlled by the basicity of amine and the nature of solvent. In addition, a possible mechanism accounting for the reaction was proposed.
متن کاملReaction between 3-hydroxy pyridine alkyl isocyanides and dialkyl acetylenedicarboxylate: synthesis of 4H-chromenes
The reactive intermediate generated by the addition of tert-butyl and 1,1,3,3-tetramethyl butyl isocyanide and cyclohexyl isocyanide to dialkyl acetylenedicarboxylate was trapped by 3-hydroxy pyridine to produce highly functionalized 4H-chromenes in fairly good yields.

متن کاملGold-catalysed cycloisomerisation reactions of 2-(2-propynyl)pyridine N-oxides leading to indolizinones.
Gold(I)-catalysed tandem oxygen-transfer/cycloisomerisation reaction of 2-(2-propynyl)pyridine N-oxides provides an atom-economical route to indolizinone frameworks.
متن کاملSolvent-Free Multicomponent Reactions of Dithiocarbamates, Activated Acetylenes and Isocyanides
An efficient method to synthesis the 2H-pyrans using three component reactions of dithiocarbamats, activated acetylenes and isocyanides in water as the solvent is described. In these reactions, synthesis of 2H-pyrans is possible based on the one-pot reaction and without using any catalyst. The mild reaction conditions and high yields of the products exhibit synthetic advantage of these methods.
