The synthetic procedures for a large-scale preparation of o- and p-nitrophenyl 2-acetamido-2-deoxy-α-D-mannopyranoside are described. The synthetic pathway employs the glycosylation of phenol with ManNAc oxazoline, followed by nitration of the aromatic moiety yielding a separable mixture of the o- and p-nitrophenyl derivative in a 2:3 ratio.
描述了一种大规模制备o-和p-硝基苯基2-乙酰氨基-2-脱氧-α-D-甘露糖苷的合成方法。该合成途径采用苯酚与ManNAc oxazoline的糖基化,然后通过芳香基的硝化产生可分离的o-和p-硝基苯基衍生物混合物,比例为2:3。
