Treatment of Ethyl 2,3 di-O-toluenesulfonyl-1-thio-beta-D-glucopyranos
ide 12 with sodium methoxide at low temperature gives Methyl 3,4 anhyr
o-6-S-ethyl-beta-D-galactopyranoside 13, whereas treatment with sodium
iodide in reluxing butanone yields 2,3 di-O-benzoyl-4-O-toluensesulfo
nyl-1,6 thioanhydro-D-glucopyranose 19.
