Carrageenans. Part X. Synthesis of 3,6-di-O-methyl-D-galactose, a new sugar from the methylation analysis of polysaccharides related to ξ-carrageenan
Abstract
3,6-Di-O-methyl-D-galactose, which had not previously been identified from natural or synthetic sources, has now been synthesised and shown to be identical with a product from the methylation analysis of polysaccharides related to ξ-carrageenan. All the possible methyl esters of D-galactopyranose are therefore now known.
