PRIMARY HYDROXY-MODIFIED CYCLOMALTOHEPTAOSE DERIVATIVES WITH 2 KINDS OF SUBSTITUENTS - PREPARATION OF -(BENZYLOXYCARBONYLAMINO)-TOSYLCYCLOMALTOHEPTAOSE, (TERT-BUTOXYCARBONYLAMINO)-TOSYLCYCLOMALTOHEPTAOSE AND ),6(V),6(VI),6(VII)-HEXA-O-TOSYLCYCLOMALTOHEPTAOSE AND THEIR CONVERSIONTO THE HEXAKIS-(3,6-ANYHDRO) DERIVATIVES

Three cyclomaltoheptaoses (1, 2 and 3) which possess a benzyloxycarbon ylamino 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 possessin g an amino group as well as other functional groups. As an example of their derivatization, their conversion to compounds containing 3,6-anh ydroglucoses, which possess cation-binding abilities, is also reported .
