3,4-Anhydro-1,6-dideoxy-1,6-episeleno-β-D-glucose was treated with cyclohexylamine to afford an amino diol which was subsequently converted into a cyclic carbamate, a compound shown to be a moderately successful glycosyl donor. Treatment of the same 3,4-anhydro sugar and the 1,6-epithio analogue with a 1-epivalienamine derivative afforded the corresponding secondary amines which were converted into the analogous cyclic carbamates. The epithio analogue was unsuccessful as a glycosyl donor, failing to glycosylate a carbohydrate alcohol. On the other hand, the episeleno compound appeared to function as a glycosyl donor but decomposition of the product occurred under the conditions necessary for its isolation.
Two carbohydrate triflates have been used to alkylate a 1-epivalienamine derivative to give small amounts of the desired secondary amines, in addition to amounts of the products of elimination. Deprotection of the secondary amines afforded a carba-disaccharide and a carba-tetrasaccharide which have been shown to be good inhibitors of β-glucosidases.
Improvements and modifications to a literature procedure for the synthesis of multigram amounts of a derivative of 1-epivalienamine are described. As well, various other derivatives of 1-epivalienamine, of potential use in the synthesis of carba sugars, are reported.
