N-碘代丁二酰亚胺和三氟甲磺酸提供了一种强大的碘离子来源，这使得通常对高氯酸二乙二胺反应迟缓的已解除武装的对4-烯基糖苷能够快速反应，并通过相邻基团的C-2酯参与显示出立体方向。
N-Iodosuccinimide and trifluoromethanesulphonic acid provide a powerful source of Iodonium ion which allows ‘disarmed’ pent-4-enyl glycosides that normally respond sluggishly to lodonium dicollidine perchlorate, to react rapidly and to exhibit stereodirection via neighbouring group participation of C-2 esters.
