that of their precursors, the enantiomerically pure cis‐ and trans‐1‐benzyl‐3‐hydroxypiperidine‐2‐methanols which were unambiguously assigned. Being configuratively fixed and conformationally constrained phosphorus analogues of acetylcholine, they mimic rotamers of acetylcholine and are suitable probes for the investigation of molecular interactions with acetylcholinesterase. As determined by kinetic methods
标题化合物为P(3)轴向和P(3)赤道取代的顺式和反式构型7-苄基-3-氟-2,4-二氧杂-7-氮杂-3-磷酸钙素3-氧化物( = 7-苄基-3-氟-2,4-二氧杂-7-氮杂-3-磷酸双环[4.4.0]癸烷3-氧化物= 5-苄基-2-氟六氢-4 H -1,3,2-二氧杂磷制备了[5,4 - b ]吡啶2-氧化物(ee> 99%)并进行了充分表征(方案2和4)。绝对构型由其前体对映体纯的顺式和反式确定明确分配了-1-苄基-3-羟基哌啶-2-甲醇。它们是乙酰胆碱的结构固定和构象受限的磷类似物,它们模拟乙酰胆碱的旋转异构体,是研究与乙酰胆碱酯酶的分子相互作用的合适探针。如通过动力学方法所确定的,所述化合物是显示出显着的立体选择性的酶的不可逆抑制剂。
