Abstract
Reported herein is a practical route to access synthetically challenging and chemoselective α,α'-diarylmethyl N-glycosides via Sc(OTf)3-catalyzed 1,6-conjugate addition of amino sugars with para-quinone methides (p-QMs). The reactions proceed smoothly without a base and under mild reaction conditions with a broad substrate scope and moderate to good yields.

Abstract
Abstract
A series of glycosyl-substituted 1,3,4-oxadiazoles were synthesized by cyclization of glycosyl-acylthiosemicarbazides via a base-catalyzed reaction. The starting glycosyl-acylthiosemicarbazide derivatives were obtained by the reaction of glycosyl isothiocyanate with various hydrazides. The acetylcholinesterase (AChE) inhibitory activities of the products were tested by Ellman’s method. The most active compounds were subsequently evaluated for the 50% inhibitory concentration (IC50) values. N-(1,3,4,6-tetra-O-benzyl-2-deoxy-β-D-glucopyranosyl)-5-(4-fluorophenyl)-1,3,4-oxadiazole-2-amine (6i) possesses the best AChE -inhibition activity with an IC50 of 1.61±0.34 μm.

Abstract
AbstractNew C2-glycosyl triazole derivatives 6a–l were synthesized by cyclization of glycosyl acylthiosemicarbazides 5 in refluxing 3 N sodium hydroxide aqueous solution. Substrates 5 were obtained by the reaction of glycosyl isothiocyanate 3 with various hydrazides. The acetylcholinesterase (AChE) inhibitory activities of compounds 6 were tested by Ellman’s method. Compounds that exhibited over 85% inhibition were subsequently evaluated for the IC50 values. Compound 6f possesses the best acetylcholinesterase-inhibition activity with IC50 of 1.46±0.25 μg/mL.

Abstract
A convenient and mild protocol for the synthesis of glycosyl 1,3,4-thiadiazole derivatives was developed, which involved the reaction of glycosyl isothiocyanate, hydrazine hydrate, and various aldehydes followed by oxidative cyclisation with ferric ammonium sulfate in methanol. 13 examples of different glycosyl 1,3,4-thiadiazole derivatives were prepared. Good yields (70–87%) have been achieved. The glycosyl 1,3,4-thiadiazole derivatives may find applications in medicinal chemistry and pharmaceutical industry.

Abstract
Green fluorescence-emitting D-glucose derivatives such as 2-NBDG have been effectively used to monitor D-glucose uptake through glucose transporters GLUTs at the single cell level. By contrast, GLUT-permeable D-glucose derivatives emitting blue fluorescence have been long awaited. A glucose tracer, 2-deoxy-2-(2-oxo-2H-chromen-7-yl)amino-D-glucose (CDG) (1), together with related compounds have been synthesized by Pd-catalyzed C-N coupling. Of these, CDG (1) is a promising blue fluorescence-emitting candidate molecule that may enter into mammalian cells through GLUTs.
