Key points in the synthesis of (−)‐hygromycin A are the tethered aminohydroxylation reaction used to prepare the aminocyclitol unit and the choice of a bulky protecting group on the sugar unit to facilitate selective Mitsunobu glycosylation and also bestow kinetic stability upon an otherwise vulnerable proton.
(-)-潮霉素A合成的关键点是用于制备氨基环糖醇单元的束缚氨基羟基化反应,以及在糖单元上选择庞大的保护基团以促进选择性的Mitsunobu糖基化,以及在原本脆弱的质子上赋予动力学稳定性。
