title: Convenient Regioselective mono-2-O-Sulfonation of Cyclomaltooctaose.
abstract: Regioselective mono-2-O-sulfonation of cyclomaltooctaose was conveniently achieved by using the combination of sulfonyl imidazole and molecular sieves in DMF. In this reaction, no 3-O- or 6-O-sulfonation products were produced. The reactions do not require strict anhydrous or basic conditions, or specific sulfonyl groups.
