The tetrazole 1 is a new β-glucosidase inhibitor (IC50=8·10−5M, Emulsin), obtained (92%) by deprotection of 22, the product of an intramolecular cycloaddition of the azidonitrile 20. This azidonitrile was formed as an intermediate by treating the L-ido-bromide 14 or the L-ido-tosylate 19 with NaN3 at 110–120°. It was isolated in a separate experiment. The yield of 22 from 19 reached 70%; 21 was formed
