    摘要:
    反应产物的定量分析表明,在55℃的吡啶中,6A,6D-双O-三苯基甲基-α-环糊精(CD),AD异构体,与三苯基氯化物反应,生成了仅为同时生成的6A,6B,6D-三O-三苯基甲基-α-CD的25%的6A,6B,6E-三O-三苯基甲基-α-CD。这表明AD异构体中葡萄糖吡喃-A和-D(Glu-A和-D)的笨重三苯基甲基基团主要在逆时针方向(分别为Glu-F和-C)上阻碍相邻葡萄糖吡喃的C(6)-OH的附加三苯基化反应。AD异构体的1H NMR光谱表明,由于三苯基甲基基团的环电流,Glu-C和-F的O(6)-H和C(6)-H信号向上移动。因此,可以得出结论,Glu-A和Glu-D上的笨重三苯基甲基基团定向到Glu-F和Glu-C,分别在Glu-F和Glu-C上立体阻碍了附加的三苯基化反应。在单6-O-三苯基甲基-α-CD、6A,6B-双和6A,6C-双O-三苯基甲基-α-CD的附加三苯基化反应中也观察到类似的立体位阻。

  • <sup>1</sup>H NMR Study of the Regioisomers of Primary<i>O</i>-Di- and Trisubstituted α-Cyclodextrins

    The regioisomers of bis- and tris[C(6)-O-sulfonylated] α-cyclodextrins were converted in satisfactory yields to the corresponding C(6)-pyridinio derivatives, which afforded the characteristic splitting patterns of 1H NMR signals available for a regioisomer determination. Electrostatic repulsive interactions between the positively charged pyridinio groups play an important role in the remarkable splitting of the 1H NMR signals observed for some regioisomers.

    analysis of the reaction products for α-cyclodextrin (α-CD) with mesitylenesulfonyl chloride (MessCl) showed that di- and tri-mesitylenesulfonylation of the primary hydroxy groups of α-CD is regioselective. The reaction of mono-6-O-mesitylenesulfonyl-α-CD with MessCl in pyridine gave less 6(A),6(C)-di-O-mesitylenesulfonyl-α-CD than 6(A),6(B)-di-O-mesitylenesulfonyl-α-CD. The reaction of 6(A),6(D)-d

  • Qualitative evaluation of regioselectivity in the formation of di- and tri-6-<i>O</i>-tritylates of α-cyclodextrin

    The quantitative analysis of reaction products showed that the reaction of 6A,6D-di-O-trityl-α-cyclodextrin (CD), AD-isomer, with trityl chloride in pyridine at 55 °C gave 6A,6B,6E-tri-O-trityl-α-CD, the amount of which was only 25% of that of simultaneously formed 6A,6B,6D-tri-O-trityl-α-CD. This indicates that the bulky trityl groups of glucopyranose-A and -D (Glu-A and -D, respectively) in the AD-isomer mainly retard the additional tritylation of the C(6)-OH of the adjacent glucopyranoses in a counter-clockwise direction (Glu-F and -C, respectively). 1H NMR spectra of the AD-isomer showed that the O(6)-H and C(6)-H signals of Glu-C and -F are shifted upfield due to the ring current of the trityl groups. Thus, it is concluded that the bulky trityl groups on Glu-A and Glu-D are oriented to Glu-F and Glu-C, respectively, and sterically retard additional tritylation on Glu-F and Glu-C. Similar steric hindrance was also observed in the additional tritylations of mono-6-O-trityl-α-CD, 6A,6B-di- and 6A,6C-di-O-trityl-α-CD’s.
