Primary hydroxy-modified cyclomaltoheptaose derivatives with two kinds of substituents. Preparation of 6I-(benzyloxycarbonylamino)-, 6I-(tert-butoxycarbonylamino)- and 6I-azido-6I-deoxy-6II,6III,6IV, 6V,6VI,6VII-hexa-O-tosylcyclomaltoheptaose and their conversion to the hexakis-(3,6-anhydro) derivatives

Abstract

Three cyclomaltoheptaoses (1, 2 and 3) which possess a benzyloxycarbonylamino group, a tert-butoxycarbonylamino group or an azido group, and six tosyloxy groups, on their C-6 atoms have been prepared. These can be versatile intermediates for the synthesis of derivatives possessing an amino group as well as other functional groups. As an example of their derivatization, their conversion to compounds containing 3,6-anhydroglucoses, which possess cation-binding abilities, is also reported.
