Efficient syntheses of two novel positional stereoisomers of valiolamine, a potent glycosidase inhibitor, and two polyhydroxy γ-amino acids are reported. The syntheses involve regio- and stereoselective azidolysis of epoxides by trimethylsilyl azide with BF3·OEt2 as Lewis acid. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
