Abstract
In carbohydrate chemistry, the synthesis of complex saccharides with well-defined structures is the most formidable process as it is quite strenuous to isolate carbohydrates in acceptable purity and amounts from natural sources. Therefore, complex saccharides with well-defined structures are often most conveniently accessed through chemical syntheses. This review mainly focuses on the methodologies for one-pot glycosylation into the complex glycans from the non-reducing end to reducing end and vice versa, orthogonal, preactivation based, photochemical as well as hybrid one-pot glycosylation. The main goal of this review in the carbohydrate community was to rapidly synthesize biologically relevant glycans that can be implemented for research in carbohydrate-based vaccine development, diagnostics, as well as drug discovery.
Keywords: Glycosylation, one-pot, carbohydrate, oligosaccharide, orthogonal, preactivation.

Catalytic C-H bond activation as a tool for functionalization of heterocycles
The major topic is the functionalization of heterocycles through catalyzed C-H bond activation. The strategies based on C-H activation not only provide straightforward formation of C-C or C-X bonds but, more importantly, allow for the avoidance of pre-functionalization of one or two of the cross-coupling partners. The beneficial impact of ...read more
