title: Preparation of di-O-triphenylmethyl-(trityl-) cyclomaltohexaoses and -cyclomaltoheptaoses and characterization of three positional isomers of each by the "hex-5-enose degradation".
abstract: Regioisomeric 6(1),6n-di-O-trityl-cyclomaltohexaoses (cG6s) or -cyclomaltoheptaoses (cG7s) were prepared by the reaction of cyclomaltohexaose (1, cG6) or cylomaltoheptaose (5, cG7) with chlorotriphenyl-methane in pyridine and isolation by h.p.l.c. The regiochemical determination of each three ditrityl-substituted derivatives has been accomplished by the "hex-5-enose degradation", followed by measurement of their f.a.b.-mass spectra.
