对称三取代的功能化α-环糊精衍生物的合成与表征
Synthesis and Characterization of Symmetrical Trisubstituted Functionalized α-Cyclodextrin
【摘要】 将α-环糊精6-位羟基进行选择性修饰,使之与过量的2-巯基吡啶在N,N-二甲基甲酰胺/碳酸钾体系中反应,合成了一种新的具有C3v对称的α-环糊精分子主体,并用核磁共振谱、电喷雾质谱等方法对其结构进行了表征.
【Abstract】 A new symmetrical trisubstituted derivative of α-cyclodextrin(α-CD), 6A,6C,6E-tri-S-2-pyridyl-2A,2B,2C,2D,2E,2F,3A,3B,3C,3D,3E,3F,6B,6D,6F-pentadeca-O-methyl-α-cyclodextrin,was synthesized by the reaction of trimesylated derivatives of α-cyclodextrin with 2-mercaptopyridine at the presence of K2CO3 in N,N-dimethylformamide(DMF).The compound was characterized by 1H,2D COSY,2D HSQC,dept-135° and dept-90° 13C NMR spectroscopy and electrospray ionization mass spectroscopy.
