M. W. Schombs, R. A. Davis, J. C. Fettinger and J. Gervay-Hague

Synopsis: The crystal structure of bridged neoglycoside, 1-deoxy-1-[(methoxy)methylamino)]-2,5-di-O-triethylsilyl-[beta]-D-glucofuranurono-[gamma]-lactone revealed a 1T2-like conformation is preferred for the furanoid ring, while the [gamma]-lactone system adopts an E4 conformation. This structure supports the properties associated with the anomeric effect for furanosides.

Formula: C20H41NO6Si2
