Abstract A mild and practically convenient one-pot procedure for the Mannich reaction via condensation of amines, aldehydes and malonates, β-ketoesters, or β-dicarbonyl compounds has been carried out without using any organic solvent, metallic catalyst, or Lewis acids or bases at room temperature. The present protocol offers several advantages, such as goods yields, simple procedure with easy workup

The three‐component Mannich reaction of among dimethyl malonate, aromaticprimary amine, and aromatic aldehyde was made successfully in the presence of solid acidic catalyst SO42−/TiO2, with excellent catalytic activity, as compared to SO42−/γ‐Al2O3 and SO42−/ZnO. To the best of our knowledge, SO42−/TiO2 prepared at varied calcination temperatures can perform different intensities of Lewis and Brønsted

The invention relates to methods and products for modulating glycosylation of proteins. The invention is useful for identifying therapeutic compounds to treat glycosylation-associated disorders such as neurodegeneration, diabetes, including complications of diabetes such as insulin resistance, nephropathy, microvascular damage, and endothelial dysfunction. The invention is also useful for identifying therapeutic compounds to treat de-glycosylation-associated disorders such as ischemic damage and traumatic injury. The invention also relates in part to assays that are useful for identifying and testing candidate compounds for modulating glycosylation of proteins and also relates in part to compounds to treat glycosylation-associated diseases and disorders.
