Amino groups are selectively protected in good yields by reaction with O-alkyl S-(pyridin-2-yl)carbonothiolates in an appropriate solvent at room temperature in air. Even glucosamine, which contains multiple hydroxyl groups, is selectively N-protected in methanol.

O-烷基 S-(吡啶-2-基)碳硫醇盐：用于氨基烷氧基羰基化的操作简单且氮选择性高的试剂

通过与 O-烷基 S-(吡啶-2-基)碳硫醇盐在适当的溶剂中在室温下在空气中反应，氨基以良好的产率被选择性地保护。甚至含有多个羟基的葡糖胺也在甲醇中被选择性地 N 保护。
