2.4.6- Tri-O-methyl-D-galactose

A methylation analysis of S14, performed in the authors laboratory,44 gave 2,3,4,6-tetra-O-methyl-D-galactose, 2,4,6-tri-O-methyl-D-galactose, and 2,3,6-tri-O-methyl-D-glucose in the proportions 1 1 1. Although these are the same components as previously reported, the proportions are different. In addition to these sugars, 2-deoxy-3-0-methyl-2-(methylamino)-D-glucose was also obtained. 

This structure was established by periodate oxidation and methyla-tion, followed by hydrolysis, as already mentioned. The formation of 2,4,6-tri-O-methyl-D-galactose and 2,6-di-O-methyl-D-galactose gave particular support to this structural proposal.
