De novo synthesis of the enantiomers Ins(1,2,3,4)P4 and Ins(1,2,3,6)P4—regiospecificity of their enzymatic dephosphorylation
摘要:
(T)he first total synthesis of Ins(1,2,3,4)P-4 and Ins(1,2,3,6)P-4 is presented. Starting from p-benzoquinone, we took advantage of the C-2-symmetry of conduritol-B intermediates. The target compounds were dephosphorylated by several enzymes, and the resulting InsP(3) isomers, were identified. Some of these enzymatic conversions were found to be preparatively applicable and to allow the synthesis of Ins(1,2,3)P-3, Ins(2,3,6)P-3 and Ins(1,2,4)P-3. (C) 2000 Elsevier Science Ltd.
