A novel class of 4,6-O-butylidene/ethylidene/benzylidene β-D-glucopyranose gelator functionalized with photo-responsiveazobenzene moieties were designed and synthesized and also characterized using different spectral techniques. These azobenzene-based organogelators can gel even at lower concentrations (critical gelation concentration – 0.5% and 1%). A morphological study of the gels shows one-dimensional

A novel class of methyltriglycol benzohydrazide based N-glycosylamines containing long alkyl chain derivatives were synthesized in good yield and characterized using NMR (1H and 13C) spectral analysis. The gelation test shows that these derivatives form gels with a wide range of polar (1,2-dichlorobenzene, chloroform) and non-polar (1,2-dichloroethane, toluene, benzene) solvents even with lower CGC

Mechanistic intermediates, and thermodynamically favored side products, in the Henry condensations of partially protected and non-protected pyranoses with a free anomeric hemiacetal function with nitromethane in various solvents for the kinetically controlled syntheses of C-glycopyranosides in the presence of DBU/molecular sieve catalyst system were identified.
