O-acylated derivatives of 1,5-dideoxy-1,5-imino-D-glucitol are disclosed that contain an N-alkyl or N-aroyl radical in which from one to four of the free hydroxyl groups are O-acylated with carboxylic alkanoyl radicals selected from the group consisting of w,w,w-trifluoro alkanoyl having from three to eight carbon atoms, carboxylic cycloalkanoyl groups having from four to eight carbon atoms and carboxylic acyclic alkanoyl groups having from two to ten carbon atoms, wherein the N-aroyl radical is selected from the group consisting of p-decylbenzoyl, 3-(p-chlorophenoxy)-propanoyl, 2-(acetyloxy)benzoyl, [1,1' -biphenyl]-4-ylcarbonyl, 2-thiopheneacetyl, trans-3-furanacryloyl, 3-methoxyphenylacetyl and 3-(trifluoromethyl)benzoyl, and wherein the N-alkyl contains from one to fourteen carbon atoms, provided that when N-alkyl contains from one to five carbon atoms the O-acylated groups are w,w,w-trifluoro alkanoyl or carboxylic cycloalkanoyl.
