“…Wang and his co‐worker prepared a number of N ‐glycopyranosylamines by condensation of p ‐aminobenzoic acid with penta‐ and hexapyranoses in ethanol/water (5:1), using acetic acid at 0 °C (entry1), as a result peracetyl derivatives were formed but with α ‐ or β ‐anomer. Kublashvili group followed the same conditions but along with p ‐aminobenzoic they also used o ‐ and m ‐aminobenzoic acids and treated with d ‐sugars and obtained a mixture of α ‐ and β ‐anomers in each case Another group.Qian and collaborators then work on it and synthesize N ‐arylglycosylamines using different type of sugars such that d ‐glucose, d ‐galactose, d ‐mannose, and d ‐xylose by reacting it with fluorinated anilines, in presence of water and a small amount of hydrochloric acid (entry 2). And as a consequence, all compounds were formed with β‐configuration stereospecifically.…”

Its even more than a centennial that the systematic researches of chemical alteration of sugars have been advancing. Out of all the interest in the field of N‐glycoside has assembled pace over the past few years. Therefore, N‐functionalization of sugar is one of the most fundamental modifications along with other group like azide, amide etc also play a remarkable role in the field of glycoscience. Different approaches to access structurally modified N‐glycosides in carbohydrate derivatives are reviewed. The goal of this review is to provide an overview of different way of N‐functionalization of amino sugar and induction of nitrogen scaffolds for the synthesis of various orthogonal protective groups of the N‐glycoside. The N‐functionalization of sugars designate as follows: (a) glycosylamine, (b) glycosyl azide, and (c) introduction of N‐functionality to the sugar for formation of N‐glycosides. This is the first review focus on N‐functionalization of sugars which will be a future scope that influence the readers to work in this area further.
