摘要:
The structure of anO-(2-acetamido-2-deoxy-α-D-galactopyranosyl)-myo-inositol isolated from human pregnancy urine has previously been identified as that of 1-O-(2-acetamido-2-deoxy-α-D-galactopyranosyl)-myo-inositol. In order to ascertain the absolute configuration in the inositol part of the compound, the 1D- and 1L- isomers were synthesised. Since none of these two stereoisomers corresponded to the natural product, the corresponding 2-O-, the mixture of the two 1DL-4-O-, and 5-O- isomers were also synthesised. None of these gave1H NMR spectra corresponding to the natural product, the structure of which therefore remains unresolved.
