New Total Synthesis of Heterocyclic Natural Products. This work provides an overview of the role of carbohydrates as precursors for the synthesis of heterocycles. It is limited to heterocycles where one or more of their carbon atoms are from carbohydrate reactants. A part of the sugar may remain linked to the heterocycles thus providing nucleoside analogues.

    Carbohydrate, class of naturally occurring compounds and derivatives formed from them. In the early part of the 19th century, substances such as wood, starch, and linen were found to be composed mainly of molecules containing atoms of carbon (C), hydrogen (H), and oxygen (O) and to have the general formula C 6 H 1 2 O 6 ; other organic.   His research is particularly focused on the synthesis of heterocycles, naturally occurring compounds, and potentially bioactive molecules. He is also involved in research projects on the carbon–nitrogen bond formation mediated by metals and metal complexes and in the synthesis of nitrogen-containing heterocycles by metathesis reactions.

Developing novel heterocycles and relating synthetic methods is the eternal goal in synthetic chemistry.

Of particular interest is the nitrogen-containing heterocycles due to their existence in many natural or synthetic molecules. Despite diverse synthetic utility, exploring.

A major fraction of the organic compounds isolated from nature are comprised of nitrogen, oxygen, or sulfur heterocycles. Nirogen-containing substances called alkaloids among them represent a majority of the important medicinal agents discovered in nature.

Recent Advances in the Synthesis of Naturally Occurring Polyhydroxylated Alkaloids. This volume describes the recent developments in the free-radical mediated synthesis and elaboration of heterocycles. The first chapter, dealing with radical cascade processes illustrates the power and the beauty of radical chemistry with some striking examples of total synthesis of complex natural heterocycles.

In this work, the synthesis of novel 1,2,4-triazole thioglycoside heterocycles 4, 5, and 8 were achieved by the reaction of 1,2,3,4,6-penta-O-acetyl-β-d-glucopyranose (2) and galactopyranose (3) with 4-((4-arylidene)amino)methyl-1,2,4-triazolethiol derivatives 1 and 6 in the presence of boron trifluoride etherate (BF 3 Et 2 O) as a promoter under nitrogen in CH 2 Cl 2.

The prevalence of nitrogen containing heterocycles in natural products and pharmaceuticals is a doubtless fact. In this review, recent applications of a stereoselective aza-Michael reaction as an efficient tool for the asymmetric synthesis of naturally occurring nitrogen-containing heterocyclic scaffolds and their usefulness to pharmacology are reviewed and summarized.
