Synthesis of myo-inositol 1,3,4,5-tetraphosphate and myo-inositol 1,3-bisphosphate

Abstract
myo-Inositol 1,3,4,5-tetraphosphate, myo-inositol 3,4-bisphosphate, and myo-inositol 4-phosphate have been prepared via routes in which a key step is a novel, highly regioselective monoalkylation of myo-inositol orthoformate.
