Background: Enantioselective reduction reactions play a key role to synthesize compounds of industrial importance. A number of metal and biocatalysts have been developed for their use in this reaction. Chiral ionic liquids (CILs) have been widely used as the reaction medium and the organocatalysts in enantioselective reduction reactions. Objective: This paper focuses on the systematic literature review about the use Read More

Background: Our research group has a longstanding interest in the synthesis of novel functionalized heteroaromatic compounds, and the development of new methods for this purpose. During our ongoing investigations, we recently had an instance to check the reproducibility of some published results concerning the chemistry of arylhydrazonals, enamines and other functionally substituted carbonyl compounds. This w Read More

Background: The synthesis of a variety of bisheterocyclic compounds has received a great attention not only as main chain polymers but also because many biologically active natural and synthetic products have molecular symmetry. In the synthesis of bisheterocyclic, researchers tried to extend the existing method by using a broad range of protocols to improve the various scope and limitations regarding their yield, purity Read More

Background: Literature data on the synthesis and structure of oximes of nucleosides and related nitrogenous bases from pyrimidine and purine were reviewed. Synthesis of novel heterocyclic systems from nucleoside oximes related pyrimidine oximes was described. The biological activity of derivatives of nucleoside and nitrogenous base oximes was also reviewed. Objective: The review focuses on the recent progress in the a Read More

Background: Amide bond formation reactions are the most important transformations in (bio)organic chemistry because of the widespread occurrence of amides in pharmaceuticals, natural products and biologically active compounds. The Beckmann rearrangement is a well-known method used for the preparation of secondary amides from ketoximes. But, most of the traditional protocols used for the Beckmann rea Read More

Aim and Objective: The objective of our work was to study the peculiarities of transformations of fluorine-containing flavone-3-carboxylates with N-nucleophiles, including biogenic amines and amino acids. Materials and Methods: 6,7,8-Trifluoro and 5,6,7,8-tetrafluoroflavone-3-carboxylates were involved in interactions with a number of N-nucleophiles, such as pyrrolidine, morpholine, proline, arginine, gammaaminobutyric acid, b Read More

Aim and Objective: In recent studies, chemistry of heterocyclic compounds, especially isoxazoles, has been widely considered by organic chemistry researchers because they have been found in many molecules, including naturally occurring bioactive compounds, pharmaceuticals, and agrichemicals. Isoxazol- 5(4H)-ones and their derivatives, on the other hand, have significant biological properties can be mentioned as Read More
