  K₂CO₃-Mediated, One-Pot, Multicomponent Synthesis of Medicinally Potent Pyridine and Chromeno[2,3-b]pyridine Scaffolds

  摘要：

  An efficient one-pot, multicomponent synthesis of 3,5-dicyanopyridines has been developed from the reaction of malononitrile and different thiophenol or thiols with a variety of aldehydes (aromatic including hindered ones, heteroaromatic, and aliphatic) in the presence of 20 mol% of K2CO3 in refluxing 50% aqeuous ethanol. KMnO4 has been utilized as a readily available, inexpensive oxidant for the in situ transformation of the initially formed dihydropyridine intermediate. K2CO3 also mediates the one-pot formation of chromeno[2,3-b]pyridines from reaction of salicylaldehyde or its analogs with malononitrile and thiol or thiophenols. Both of these conditions also work equally well under 50-fold scale-up conditions.Supplemental materials are available for this article.

  Borax, an innocuous, inexpensive, and a naturally occurring material, very efficiently catalyzes the Knoevenagel condensation and Michael addition in domino fashion for the construction of highly functionalised pyridines, dienes, anilines and dihydropyrano[3,2-c]chromenes. The present protocol offers advantages in terms of higher yields, wide scope of substrates, operational simplicity, short reaction time, no requirement of workup or column chromatography, and easy access to a wide range of structurally diverse functionalized molecules of biological importance. Recycling of the catalyst and scaling up of the reactions are important attributes of this catalytic process.
