The Structure Of Hexa‐O‐acetyl‐α‐d‐fructofuranose‐β‐d‐fructofuranose 1,2′:2,6′‐Dianhydride

Abstract

The crystal structure of 3,4,6,1′,3′4′‐hexa‐O‐acetyl‐α‐d‐fructofuranose‐β‐d‐fructofuranose 1,2′:2,6′‐dianhydride, 1, has been determined. The central, eight‐membered 1,3,6‐trioxacane ring is in a twist‐boat‐chair conformation. Molecular modeling has shown that this conformation is inherent and not due to crystal packing forces and is also the most likely conformation present in underivatized α‐d‐fructofuranose‐β‐d‐fructofuranose 1,2′:2,6′‐dianhydride.
