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. The following heterocycles were included: furans, pyrrols, thiophenes, pyrazoles, imidazoles,...
The high synthetic versatility exhibited by the isothiocyanato motif has allowed its use as a building block in the preparation of a plethora of derivatives. When present in carbohydrates, the strong electrophilicity shown by isothiocyanates, together with the possibility of undergoing cycloaddition reactions has made it possible to access a broad spectrum of heterocyclic compounds, of either synthetic...
This review is devoted to the stereoselectivity of intermolecular (intramolecular cycloadditions are not included) 1,3-dipolar cycloadditions of sugar-derived nitrones. Stereoselective cycloaddition (transformation of isoxazolidine followed by reduction of the N–O bond to produce both an amino and a hydroxy function) allows the synthesis of tailor-made products of possible biological interest such...
