Tris(pentafluorophenyl)borane-promoted stereoselective glycosylation with trichloroacetimidate glycosyl donors is described. The reactions proceed efficiently with a wide range of acceptors, from sugar to nonsugar, under mild conditions in the presence of a catalytic amount of B(C₆F₅)₃. The perbenzylated glucosyl α-imidate provides β-selective glycosides in 70–92% yields.

在温和条件下，三（五氟苯基）硼烷促进的糖基三氯乙酰胺酸酯的立体选择性糖基化

描述了用三氯乙酰亚胺酸酯糖基供体的三（五氟苯基）硼烷促进的立体选择性糖基化。在催化量的B（C ₆ F ₅）₃存在下，在温和条件下，反应可利用各种受体（从糖到非糖）有效地进行。过苄基化的葡萄糖基α-亚氨酸酯以70-92％的产率提供β-选择性糖苷。
