  摘要：

  Regioselective monoacetylation of 2-allyloxycarbonylamino-1,6-anhydro-2-deoxy-beta-D-glucopyranose (1) gave a mixture of 3-O-acetyl and 4-O-acetyl derivatives, the structures of which were established by two-dimensional, phase-sensitive NOESY and confirmed by chemical proofs. The benzylation of 1, on the other hand, led to 2-allyloxycarbonylamino-1,6-anhydro-3,4-di- (5) or 2-allyloxycarbonylamino-1,6-anhydro-2 -N-benzyl-3,4-di-O-benzyl-2-deoxy-beta-D-glucopyranose (10). The regioselective cleavage of 5 with titanium tetrachloride gave the expected 3-O-benzyl derivative, the structure of which was ascertained by chemical proofs; the same reaction performed on 10 led to the opening of the anhydro ring to afford 3-benzyl-[3,4-di-O-benzyl-1,2-dideoxy-alpha-D-glucopyrano]-[2,1-d]-2-oxazolidone.
