Efficient syntheses of three novel scaffolds for potential β‐glycosidase inhibitors were developed: The first consists of a 2,7‐dioxabicyclo[2.2.1]heptane derivative, which was prepared by an intramolecular ketalisation. The second scaffold consists of a hydroxylated cyclopentylamine, which could be synthesised stereoselectively from 2‐azabicyclo[2.2.1]hept‐5‐en‐3‐one. The third scaffold, a 4,5‐dihydroxynicotinic acid, was accessible through a sequence of substituent directed ortho ‐lithiations. Selected compounds were tested as inhibitors for a number of glycosidases. Three nicotinic acid derivatives were found to be selective β‐glucosidase inhibitors.(© Wiley‐VCH Verlag GmbH & Co.
