| Abstract: | Syntheses of a metabolite of the second messenger myo-inositol 1,4,5-trisphosphate, myo-inositol 1,4-bisphosphate, and an analogue, the 1,4-bisphosphorothioate, are reported, by using phosphite chemistry on (+/-)-1,2:4,5-di-isopropylidene-myo-inositol. The synthesis of (+/-)-1,2:4,5-di-isopropylidene 3,6-bis[di-(2-cyanoethyl)]phosphite provides an intermediate that can be oxidized to either the corresponding bisphosphate or bisphosphorothioate. myo-Inositol phosphorothioates are proposed as novel analogues of myo-inositol phosphates; their resistance to phosphatase-catalysed breakdown is reported. |
