Preparation of di-O-triphenylmethyl-(trityl-)cyclomalto-octaoses, and isolation and characterization by 'hex-5-enose degradation' of four positional isomers
Four regioisomeric ditritylated derivatives of cyclomalto-octaose (1, cG8), namely, 61,6(n)-di-O-trityl-cG8s have been prepared by the reaction of 1 with chlorotriphenylmethane in pyridine and isolated by high-performance
