procedure was employed to prepare a novel series of pyridine glycosides. The protocol allows the reaction of 2-pyridone with 1,2,3,4,6-penta-O-acetyl-α-D-glucopyranose under solvent-free microwave-assisted synthesis using different solid supports. Silica gel has been found to be an efficient and environmentally friendly promoter. Structures of the new products were confirmed based on their elemental analyses
一种有效,温和,快速的程序用于制备一系列新的吡啶苷。该方案允许2-吡啶酮与1,2,3,4,6-戊-O-乙酰基-α -D-吡喃葡萄糖在无溶剂的微波辅助合成下使用不同的固体载体反应。已经发现硅胶是有效和环保的促进剂。根据新产品的元素分析和光谱数据(LC-MS / MS,IR,UV,1D和2D-NMR)确定了新产品的结构。
