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.

Stereoselective synthesis of 6-deoxy and 3,6-dideoxy-D-myo-inositol precursors of deoxy-myo-inositol phosphate analogues from D-galactose
摘要:
The synthesis of chiral protected D-6-deoxy-myo-inositol derivatives from D-galactose is described. Ferrier rearrangement of hexenogalactopyranosides has been employed to produce the corresponding 6-deoxy-cyclohexanone polyols. The stereoselectivity of the carbocyclic transformation was discussed on the basis of the experimental data and a mechanism has been proposed. From deoxy-inososes, the access to a variety of 6-deoxy and 3,6-dideoxy-myo-inositol was performed to prepare suitable monool, diol and triol precursors for the synthesis of D-deoxy-myo-inositol phosphate analogues.
