摘要：

The formal synthesis of benzyl 2,3-aziridino-N-(benzyloxycarbonyl)-2,3-dideoxy-γ-butyrolactone (21) from D-ribose is described. Reaction of 21 with excess benzyl alcohol in the presence of boron trifluoride etherate and hydrogenolysis of the product gave (3S,4S)-dihydroxy-L-glutamic acid ((3S,4S)-3).
