Total synthesis of the second messenger analogue D-myo-inositol 1-phosphorothioate 4,5-bisphosphate: optical resolution of DL-1-O-allyl-2,3,6-tri-O-benzyl-myo-inositol and fluorescent labelling of myo-inositol 1,4,5-trisphosphate

is(2-cyanoethoxy)thiophospho]-4,5-bis[bis(2-cyanoethoxy)phospho]-myo-inositol. Deblocking afforded racemic myo-inositol 1-phosphorothioate 4,5-bisphosphate, which was reacted with the iodoketone of a fluorescent label to generate a fluorescently labelled inositol 1,4,5-trisphosphate analogue. DL-1-O-Allyl-2,3,6-tri-O-benzyl-myo-inositol was resolved into its enantiomers by means of the crystalline
用于合成两条路线肌醇肌醇1,4,5-三磷酸类似物肌醇肌醇-1-磷酸酯4,5-二磷酸已经设计。DL -2,3,6-三- ø -苄基-1- Ö - (顺式-丙-1-烯基) -肌醇肌醇制备自DL -1- ø -烯丙基-2,3,6-三Ø苄基肌肌醇和磷酸化来保护4,5-二磷酸。除去丙烯基团产生的DL -1,2,4-三-O-苄基-5,6-双[双(2-氰基乙氧基)磷酸]-肌醇被硫代磷酸化,得到DL-2,3,6-三ø -苄基-1- ö - [二(2-氰基乙氧基)thiophospho] -4,5-二〔二(2-氰基乙氧基)磷酸] -肌醇肌醇。脱保护得到外消旋的肌-肌醇1-硫代磷酸酯4,5-双磷酸酯,其与荧光标记的碘酮反应生成荧光标记的肌醇1,4,5-三磷酸类似物。借助结晶的4,5-双樟脑酸酯将DL -1- O-烯丙基-2,3,6-三-O-苄基-肌醇分解为对映体。1和d - (+) - 1- ø -烯丙基-2
