Abstract
Improvements in the preparation of a key imidazylate and the reduction of the derived nitrile have led to more efficient syntheses of isofagomine, noeuromycin, azafagomine, and isofagomine lactam. As well, a precursor of azafagomine has been converted into azanoeuromycin, and the nitrogen atom of isofagomine has been incorporated into a guanidine residue.
Acknowledgments
We thank Ian D. Jenkins for suggesting the guanidine 6 as an interesting synthetic target, and Gideon Davies and Tracey Gloster for investigating its potential as an inhibitor of glycosidases.
