5-tris[di(2-cyanoethyl)phosphate] which was also obtained from the 4,5-bis[di-(2-cyanoethyl)phosphate]. Both the tris[di-(2-cyanoethyl)phosphate] and the tris(dibenzyl phosphate) are intermediates suitable for the synthesis of 1,4,5-IP3.
摘要外消旋1,2,4-三-O-苄基-肌醇3- [二-(2,2,2-三氯乙基)磷酸酯]与双(2,2,2-三氯乙基)磷酸氯酯的反应3,5-和3,6-双磷酸酯衍生物,它们难以分离并且不能进一步磷酸化。通过将外消旋的1,2,4-三-O-苄基-肌醇[由1,2, [4-三-O-苄基-3,5-和-3,6-二-O-(顺-丙-1-烯基)-肌醇]和随后的酸性水解。将1 d -2,3,6-三-O-苄基-1,4-二-O-(顺-丙-1-烯基)-肌醇转化为结晶1 d -2,3,6-tri -O-苄基-肌醇1,4-双(磷酸二苄基酯),进而得到结晶的1,4,5-三(磷酸二苄基酯),使用来自1 d -2,3,6-tri-O-苄基-肌醇的二苄氧基(二异丙基氨基)膦。使用双(2-氰基乙氧基)(二异丙基氨基)膦将后一种化合物转化为结晶的1,4,5-三[二(2-氰基乙基)磷酸酯],其也从4,5-双[二-(2-氰基乙基)磷酸酯]。磷
