A short stereoselective synthesis of (+)-aza-galacto-fagomine (AGF)

A catalytic asymmetric synthesis of (+)-aza-galacto-fagomine (AGF) - the most promising compound for the pharmacological chaperone therapy of Krabbe disease was accomplished in six steps, in 14% overall yield. The synthesis hinges on the combination of organocatalyzed aldolization and reductive hydrazination.
