描述了一种大规模生产1-苯磺酰基哌啶和其他亚磺酰胺的改进方案。结果表明,在三氟甲磺酸酐介导的硫糖苷活化中,1-苯亚磺酰基吡咯烷和N,N-二乙基苯亚磺酰胺的作用类似于1-苯亚磺酰基哌啶,而且它们的结晶性较弱,因此它们可在-78°C下使用到将1-苯亚磺酰基哌啶保持在溶液中所需的-60°C。N,N-二环己基苯磺酰胺不会与三氟甲磺酸酐结合活化硫糖苷,这归因于其较大的空间体积。*致谢Jacques H. Van Boom教授。

piperidine in the trifluoromethanesulfonic anhydride‐mediated activation of thioglycosides, and that their less crystalline nature enables them to be used at −78°C as opposed to the −60°C required to keep 1‐benzenesulfinyl piperidine in solution. N,N-Dicyclohexyl benzenesulfinamide does not activate thioglycosides in combination with trifluoromethanesulfonic anhydride, which is attributed to its greater steric
