Conclusions
-
1.
The product of the isomerization of 1,6-anhydro-2-desoxy-2,4-di-C-methyl-3-O-benzyl-4-O-mesyl-β-D-galactopyranose corresponds in structure to 1,6-anhydro-2-desoxy-2,4-di-C-methyl-3-O-benzyl-5-O-mesyl-α-L-idofuranose. The geometrical and conformational parameters of this compound were determined.
