Stereoselective synthesis of inositol mono, bis and trisphosphate analogues from 6-deoxy- d -inositol precursors
摘要:
The synthesis of opticaly pure deoxy-myo-inositol mono, bis and trisphosphate analogues is described from 4-O-benzyl-2,3-di-O-cyclohexylidene-6-deoxy-myo-inositol and corresponding 1,5 epimer chiro-inositol. These precursors, which derive from galactose, are used to accede to a variety of cyclitol intermediates employing protection/deprotection sequence. The phosphorylation procedure was performed to produce free and original substituted phosphate derivatives aimed to be incorporated through the lipidic cell membrane for in vivo evaluation.

The synthesis of 6-deoxy-D-myo-inositol-1,3,4,5-tetrakisphosphates is described. The access to opticaly pure Ins(1,3,4,5)P-4 analogues was carried out from deoxy myo inositol precursors derived from D-galactose. Modification of Ins(1,3,4,5)P-4 analogues by lipophilic substituents has been investigated in order to produce neutral phosphate derivatives aimed to be incorporated in cell membrane for in vivo evaluation.
