    • The present invention relates to a process for preparation of a product compound of the Formula (I), where R 1 is an acyl group, R 2 is H, an N-alkylated amino sugar, or a non-basic sugar moiety, and R 3 is H, OH, or OCH 3 . The process involves reacting a starting compound of the Formula (II) with an acyl donor compound in the presence of a non-chemically modified lipase, under conditions effective to produce the product compound. Another aspect of the present invention relates to a compound of the following Formula (III), where: R 1 is an acyl radical of a carboxylic acid selected from the group consisting of: polyethylene glycol acetic acid and polyunsaturated fatty acid; and R 2 = 2,6-dideoxy-2-fluoro-α-talopyranosyl; 3-trifluoroacetylamino-2,3,6-trideoxy-α-L- lyxo -hexopyranosyl; or 3-deamino-3-(2'-pyrroline-1'-yl)-2,3,6-trideoxy-α-L- lyxo -hexopyranosyl; or a pharmaceutically acceptable salt thereof. The present invention also relates to a compound of the Formula (IV) where n is 4 or 5, or a pharmaceutically acceptable salt thereof. Another aspect of the present invention relates to a compound of the Formula (V) where: R 1 is an acyl group, R 2 is 3-substituted allyloxycarbonylamino-2,3,6-trideoxy-α-L- lyxo -hexopyranosyl, R 3 is H, OH, or OCH 3 .
