多重保护的2-叠氮基-2-脱氧-D-吡喃葡萄糖通过相应糖醛的叠氮基苯基硒化，然后水解所得硒代糖苷来制备：从受保护的D-半乳醛中获得受保护的2-叠氮基-2-脱氧-D-吡喃半乳糖，作为唯一产物，总产率为72%。
Diversely protected 2-azido-2-deoxy-D-glycopyranoses are prepared by azido phenylselenylation of the corresponding glycal followed by hydrolysis of the resulting selenoglycosides: from protected D-galactal, protected 2-azido-2-deoxy-D-galactopyranose is obtained, as the sole product in 72% overall yield.
