Enzyme assisted synthesis of enantiomerically pure myo-inositol derivatives - chiral building blocks for inositol polyphosphates
摘要:
Using a short and facile synthetic protocol involving highly selective, regio- and enantioselective enzymatic esterifications as key reaction steps, readily available myo -inositol is converted into optically pure 1D-1-O-butyryl-4,6-O-dibenzoyl-myo-inositol (-) - 5, a selectively protected central intermediate for the preparation of numerous inositol phosphates.

The title compound is prepared in enantiomerically pure form via a facile enzyme assisted route. Essential for the success of the described method were a) the highly enantioselective esterification of 4,6-O-dibenzoyl-myo-inositol 2, b) the selective acylation of the axial hydroxyl function in 3 and c) the selective, base catalysed methanolysis of one benzoate group in 5. The obtained, selectively protected 1,2,6-triol 6 was converted into the title compound 7 by phosphorylation using N,N-dimethyl dibenzyl phosphoamidite followed by deprotection.
