Trehalose 6-0-mesyl

DMF). Monomolar palmltoylatlon of sucrose gave b-O-palnltoyl-sucrose this Is In contrast to t-butyldlphenylsllylatlon. In which the etherification occurs on the 6-hydroxy group of the fructose unit (see Vol. 16, p.55 ref.35). The synthesis of 6-0-mycolyl- and 6- -corynomycolyl-oc, <-trehalose, related to the trehalose mycolates widely distributed in mycobacteria, has been achieved via the key step of mesylate displacement with potassium mycolate or corynomyco-late (see also refs.48 and 49). 

The trehalose derivatives 3-0-benzyl-4,6-0-benzylidene-2-deoxy-a-D-ri/>o-hexopyranosyl 4, 6 -0-benzylidene-2 -deoxy-a-D-rifto-hexopyranoside and 2,2, 3,3 -tetra-0-benzoyl-6,6 -dideoxy-4,4 -di-0-mesyl-6,6 -dithiocyanato-a,o-tre-halose di-iV-acetylchitobiose complexed to turkey egg lysozyme. ...
