摘要:
The 3-mono-, 3,4-bis-, and 3,4,5-trisphosphates of L-alpha-phosphatidyl-D-myo-inositol have been synthesized in their optically active forms from the two enantiomers of 1,2:5,6-di-O-cyclohexylidenemyo-inositol. These chiral precursors were prepared by a facile biocatalytic resolution, in which the 8-butyryl ester of the racemic compound was subjected to enantioselective hydrolysis by porcine pancreatic lipase in a biphasic system. The overall yield from individual chiral precursors ranged from 32% for the 3,4,5-trisphosphate to 39% for the monophosphate.
