Key points in the synthesis of (−)‐hygromycin A are the tetheredaminohydroxylation reaction used to prepare the aminocyclitol unit and the choice of a bulky protecting group on the sugar unit to facilitate selective Mitsunobuglycosylation and also bestow kinetic stability upon an otherwise vulnerable proton.
