A new glycosyl donor possessing an anomeric O-(1-phenyltetrazol-5-yl) group is prepared from 2,3,4,6-tetra-O-benzyl-D-glucose (2) and commercially available 5-chloro-1-phenyl-1H-tetrazole (1). The synthesis of glycosides derived from the donor and a few primary and secondary alcohols is reported.

Inhibitors of 11beta-hydroxysteroid dehydrogenase (11beta-HSD1) show promise as drugs to treat metabolic disease and CNS disorders such as cognitive impairment. A series of 1,5-substituted 1H-tetrazole 11beta-HSD1 inhibitors has been discovered and chemically modified. Compounds are selective for 11beta-HSD1 over 11beta-HSD2
