Abstract

The hydroxyl group at C-5 in racemic 1,2-O-Cyclohexylidene-myo-inositol (rac-1) was regio- and enantioselectively acylated to give 5-O-acetyl- (2a)- or 5-O-butyryl-2,3-O-cyclohexylidene-myo-inositol (3a), respectively, by treatment of 1 with vinyl acetate or 2,2,2-trifluoroethyl butyrate in the presence of crude porcine pancreatic lipase in various organic solvents. Compound 2a was phosphorylated and deprotected to give myo-inositol 1,4,6-trisphosphate (8). Compound 2a was deacetylated and the resulting 2,3-O-cyclohexylidene-myo-inositol (1) was converted to myo-inositol 1,4,5,6-tetrakisphosphate (6).
