A series of five new macrocyclic hybrids with a sucrose scaffold were prepared by the reaction of activated 1′,2,3,3′,4,4′-hexa-O-methylsucrose with diversely functionalized d-mannitols. The 21-, 25-, and 31-membered representatives containing mannitol units were prepared by a macrocyclization of 6,6′-di-O-propargylated sucrose with protected 1,6-diazido-d-mannitol or 6,6′-di-azidosucrose with propargylated d-mannitol (a “click” approach), whereas 23-membered representatives were prepared by double N-alkylation of 1′,2,3,3′,4,4′-hexa-O-methyl-6,6′-di-aminosucrose with 1,6-di-bromoacyl d-mannitol. All sucrose derivatives were tested as putative hosts for chiral recognition of α-phenylethylammonium (α-PEA) cations. In one case, in striking contrast to all sucrose-based macrocyclic hosts previously reported by us, unexpected reverse preference for the R-enantiomer was observed (KR/KS = 1.5).

The chemistry of sucrose is very challenging due to its eight hydroxyl groups, three of which are primary, with very similar reactivities, thus control of the chemoselectivity is a central issue. In this work, the selective formation of monounsaturated es

The glycosidase inhibitor 1-deoxymannonojirimycin (1,5-dideoxy-1,5-imino-D-mannitol) was synthesized in four simple steps from sucrose via 6,6'-diazido-6,6'-dideoxysucrose and 6-azido-6-deoxy-D-fructofuranose.The "isomeric ballast" of the sequence, 6-azido-6-deoxy-D-glucose, could be partially converted into 6-azido-6-deoxy-d-fructofuranose with the aid of glucose isomerase (E.C. 5.3.1.5) demonstrating a novel synthetic application of this enzyme.The sequence allows access to multigramm quantities of 1-deoxy-mannonojirimycin in over 30percent overall yield without the need for expensive reagents and protecting group manipulations.Key Words: 1-deoxymannonojirimycin, mannosidase inhibitor, glucose isomerase, sucrose, synthesis
