  Synthesis of Optically Pure 3,4-Disubstituted l-Glutamates from a Novel 2,3-Aziridino-γ-lactone 4-Carboxylate Derivative

  摘要：

  The synthesis of the N-acetyl and N-Cbz derivatives of (1S,4S,5R)-4-(methoxycarbonyl)-3-oxa-6-azabicyclo[3.1.0]hexan-2-one (24 and 27, respectively) from D-ribose is described. While compound 24 reacted with methanol in the presence of boron trifluoride etherate to give the novel 2,3-iminoglutamate derivative 28, compound 27 afforded, under the same conditions, the 4(S)-hydroxy-3(S)methoxy-L-glutamate 31. Similarly, reaction of 27 with ethanol and benzyl alcohol gave the corresponding 3(S)-ethoxy and 3(S)-(benzyloxy) analogues of 31. This represents the first example of the use of a carbohydrate for the preparation of L-glutamate derivatives as well as the first example of a stereocontrolled synthesis of glutamate analogues dissymmetrically substituted at the beta,gamma-positions.

  Several N-substituted methyl 2,3-dideoxy-2,3-epimino-β-D-lyxofuranosides are described, including compounds in the 5-deoxy-series. In most cases, the epimines were synthesized from the appropriate 3-azido-3-deoxy-2-p-tolysulphonyloxy-xylo-derivatives, which in turn were prepared from the 2,3-bis-p- tolysulphonyloxy-ribo-compounds. The azidolysis of methyl 2,3-N-benzoylepimino-2,3-dideoxy-β-D-lyxofuranoside is described.
