2-Amino glucose ((2S,3R,4S,5S,6R)-2-amino-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol) as a substrate for the synthesis of NiFe2O4@SiO2@amino glucose supply an environmentally friendly procedure for the synthesis of bis(1,2-dihydro-4-hydroxy-2-oxoquinolin-3-yl)methanes through one-pot condensation of aldehyde or pyrazolo carbaldehyde and two equivalents of 4-hydroxyquinolin-2(1H)-ones in aqueous
以2-氨基葡萄糖((2S,3R,4S,5S,6R)-2-氨基-6-(羟甲基)四氢-2H-吡喃-3,4,5-三醇)为底物,用于合成NiFe2O4 @ SiO2氨基葡萄糖提供了一种环境友好的程序,可通过一锅缩合醛或吡唑甲醛和两当量的4-羟基喹啉来合成双(1,2-二氢-4-羟基-2-羟基-2-氧喹啉-3-基)甲烷在水性介质中为-2(1H)-one。生态友好,所需产物的纯度高,反应时间短和后处理步骤容易,是该方法的其他优点。合成的4-羟基-2(1H)-喹诺酮化合物的结构通过1H,13C NMR和FTIR光谱数据以及元素分析确定。
