本文报道了七种新的糖基N -对甲苯磺酰基苯甲亚胺酯，它们是由相应的半缩醛与亚氨酰氯反应制得的，产率为55-88%，经醇处理和TMSOTf催化后，顺利地转化为糖苷，产率为57-99%，
Seven novel glycosyl N -tosyl benzimidates were prepared by the reactions of the corresponding hemiacetals with imidoyl chloride in 55–88% yields, which were smoothly converted to glycosides, upon treatment with alcohols and catalytic TMSOTf, in 57–99% yi
