l) trisphosphate 6 was obtained. For DL-3-O-alkylated myo-inositol 1,4,5-trisphosphate analogues, the fully protected 14 was isomerized to the cis-prop-1-enyl derivative 15. The propenyl group was removed to give DL-2,6-di-O-benzyl-1-O-(p-methoxybenzyl)-4,5-isopropylidene-myo-inositol (16). The 3-O-methyl ether 17, 3-O-ethyl ether 18, and 3-O-n-propyl ether 19 derivatives were synthesized by treatment
已经设计了从肌醇合成外消旋形式的3-O-(羧甲基)-和3-O-烷基化肌醇1,4,5-三磷酸酯的方法。对于DL-3-O-(羧甲基)-肌醇1,4,5-三磷酸酯,肌醇1,3,4,5-四磷酸酯的类似物,DL-3-O-烯丙基-2,6-由肌醇从七步制备二-O-苄基-1-O-(对甲氧基苄基)-4,5-O-异亚丙基-肌醇(14)。用酸处理14后获得的三醇DL-3-O-烯丙基-2,6-二-O-苄基-肌醇(26)被磷酸化,产物被氧化,得到完全保护的三磷酸酯27在氰基乙基保护的磷酸三酯存在下,27的3-O-烯丙基醚的有效氧化裂解是通过用NaIO(4)/ RuCl(3)处理27实现的。水合得到完全保护的3-O-(羧甲基)三磷酸酯28。解封后,得到DL-3-O-(羧甲基)三磷酸酯6。对于DL-3-O-烷基化的肌醇1,4,5-三磷酸类似物,将完全保护的14异构化为顺式-丙-1-烯基衍生物15。除去丙烯基,得到DL-2
