Progress in the Chemistry of C-Glycosylation in Carbohydrates
Abstract: Glycosylation is an intricate biochemical process where a glycosyl donor and a glycosyl acceptor are combined to form a glycoside. This process involves the creation of new stereogenic centers at the anomeric site of the glycosyl donor, leading to the formation of a diverse array of products. By establishing glycosidic linkages, the synthesis of complex polysaccharides becomes possible, opening doors to the creation of analogues for further exploration of their …

An Efficient Synthesis of Some Novel Benzo Coumarin Derivatives Under Solvent Conditions from 2-acetyl-benzo[f]chromen-3-one
Abstract: The synthesis of the target compounds began with the preparation of 2-[3-dimethylamino[acryloyl-3H-benzo[f]chromen-3-one. This intermediate was obtained through the reaction of 2-acetylbenzo[f]coumarin-3-one with N,N-dimethylformamide dimethyl acetal [DMFDMA[ under reflux conditions in xylene. The enaminone thus formed was subsequently reacted with 6-aminothiouracil in acetic acid, leading to the formation of 2-thioxo-2,3-dihydro-1H-pyrido[2,3-d]pyrimidin-4-one. This compound served as a pivotal intermediate for the synthesis of a series of pyridotriazolopyrimidinones. These derivatives were synthesized by reacting …
