  Divergent Syntheses of All Possible Optically Active Regioisomers of myo-Inositol Tris- and Tetrakisphosphates

  摘要：

  Since the discovery Of D-myo-inositol 1,4,5-trisphosphate, which plays a pivotal role as a second messenger in transmembrane signaling, the scope of the phosphoinositide-based signaling processes has been continually expanding. However, the clear understanding of the molecular signal transduction mechanisms including the functions of newly found IPn is still lacking. As a continuing effort to our previously reported syntheses of all possible 39 optically inactive regioisomers of myoinositol phosphates (IPn; n = 1-6), we synthesized all possible optically active regioisomers of myo-IP3 and myo-IP4 using chiral IBz(3)s and IBz(2)s, respectively. A series of procedures involving CRL-catalyzed enzymatic resolution of racemic 1,2:5,6-di-O-isopropylidene-myo-inositoI and base-catalyzed benzoyl migration in tri- and dibenzoyl-isopropylidene-myo-inositol afforded eight enantiomeric pairs of IBz(3) and six enantiomeric pairs of IBz(2), respectively. Phosphorylation of these intermediates by the phosphitylation and oxidation procedure gave the target products.
