Preparation of Hexakis(6-O-mesitylsulfonyl)cyclomaltooctaoses and Structural Validation of the Four Isomers Using Heteronuclear Multiple Bond Correlation Spectroscopy

Four cyclomaltooctaose derivatives 1a–d, which possess six mesitylsulfonyloxy groups on their C(6) atoms, were prepared. The assignment of the regiosiomers was performed by observing the long-range coupling through a glycoside linkage between H(1′) –C(4) and C(1′) –H(4) using a heteronuclear multipl...

Zusammenfassung:Four cyclomaltooctaose derivatives 1a–d, which possess six mesitylsulfonyloxy groups on their C(6) atoms, were prepared. The assignment of the regiosiomers was performed by observing the long-range coupling through a glycoside linkage between H(1′) –C(4) and C(1′) –H(4) using a heteronuclear multiple-bond correlation (HMBC) method.
