METHYLATION OF METHYL 6-O-TRITYL-α-D-MANNOPYRANOSIDE - A NEW ROUTE TO THE SYNTHESIS OF SOME METHYL ETHERS OF D-MANNOSE

Article abstract of DOI:10.1007/BF00575691

The partial methylation of methyl 6-O-trityl-α-D-mannopyranoside by Kuhn's method (BaO, Ba(OH)2*8H2O, CH3I) in dimethylformamide and dimethyl sulfoxide has been studied.Simple methods are proposed for obtaining the 3- and 4-mono-O-, the 2,3-, the 2,4- and 3,4-di-O-, and the 2,3,4-tri-O-methyl ethers of methyl 6-O-trityl-α-D-mannopyranoside.
