  描述：

  benzyl 2,2,2-trifluoro-N-(4-nitrophenyl)acetimidate 、 1,2,3,4-四-O-乙酰基-β-D-葡萄吡喃糖 在 三氟甲磺酸三甲基硅酯 作用下， 以 二氯甲烷 为溶剂， 反应 1.17h， 以83%的产率得到1,2,3,4-tetra-O-acetyl-6-O-benzyl-β-D-glucopyranose

  名称：

  The development of N-aryl trifluoroacetimidate-based benzyl and allyl protecting group reagents

  摘要：

  An exploration of the role of para-substituents on the balance between stability and reactivity of N-phenyl trifluoroacetimidates prompted the discovery of new reagents for the addition of allyl and benzyl protecting groups, namely O-allyl and O-benzyl N-(p-nitrophenyl)trifluoroimidates. These compounds are stable and crystalline at ambient temperature, making them ideal alternatives to existing benzylating and allylating reagents used under acidic conditions. (C) 2013 The Authors.
