Description
技术领域
本发明属于药物合成技术领域,尤其涉及一种不对称氢化构建卢美哌隆中间体的方法及卢美哌隆中间体。
背景技术
卢美哌隆(通用名:Lumateperone tosylate,商品名为Caplyta),化学名为:1-(4-fluorophenyl)-4-((6bR,10aS)-3-methyl-2,3,6b,9,10,10a-hexahydro-1Hpyrido[3',4':4,5]pyrrolo[1,2,3-de]quinoxalin-8(7H)-yl)butan-1-one,4-methylbenzene-sulfon ate。卢美哌隆甲磺酸盐的分子量:393.50;CAS登记号:1187020-80-9(Lumateperone tosylate),313368-91-1(Lumateperone);结构式为式I所示:
抗精神病药卢美哌隆Lumateperone由生物制药企业Intra-CellularTherapies开发,2019年12月获美国食品药物监督管理局(FDA)批准上市,用于成人精神分裂症的治疗。卢美哌隆Lumateperone是精神分裂症治疗领域的首创新药,可协同作用于5-羟色胺、多巴胺及谷氨酸能系统,其独特的作用机制使得该药不仅能改善精神分裂症患者的阳性症状,亦对阴性症状及抑郁症状有效,常见的不良反应有镇静、头痛、腹泻、口干等。
现有技术文献:非专利文献(J.Med.Chem.2014,57,2670-2682),报道以3,4-二氢-1H-2-喹喔啉酮为原料,经亚硝化、还原、Fischer吲哚反应构建含六氢-γ-咔唑四环结构,然后经氰基硼氢化钠还原、酰胺甲基化、酰胺还原、酰胺水解得到消旋的顺式四环母核,然后与卤代酮N-烷基化反应,得到消旋体卢美哌隆,最后经手性HPLC拆分得到目标产物卢美哌隆(Scheme 1,路线一)。该路线原料昂贵,路线长,使用大量潜在的剧毒试剂氰基硼氢化钠作为还原剂,废液对环境有影响,最后的步骤使用手性拆分得到目标产物,产率低,利用率低。路线二以盐酸邻溴苯肼伪原料,经Fisher吲哚反应、硅氢还原、N-酰化反应、钯催化C-N键偶联反应、N-烷基化反应、亚胺水解和酰胺化反应、酰胺烷基化、酰胺还原、烷氧酰胺水解得到四元环母核,然后经手性HPLC制备得到手性的四元环母核,最后与烷基酮N-烷基化反应得到目标产物卢美哌隆。该路线同样路线长,使用大量的还原剂,使用贵金属钯催化偶联,最后使用手性HPLC拆分得到关键母核,同样产率低、产品利用率低(Scheme 1,路线二)。以上路线都不具有工业应用价值。
专利(WO 2008112280)技术路线如Scheme 2所示。同样以2-溴苯肼盐酸盐与4-哌啶酮盐酸盐为原料合成邻溴六氢-γ-咔唑,接着硅氢化还原、(S)-(+)-扁桃酸成盐拆分得到光学纯的邻溴八氢-γ-咔唑,然后哌啶环N-烷氧羰基化,氢化吲哚环N上烷基化、铜催化Ullman偶联构建四元环,最后硼氢化还原酰胺,得到卢美哌隆关键中间体。
专利(CN 113024554 A)报道的技术路线,通过2-溴苯肼盐酸盐与4-哌啶酮盐酸盐一水化合物反应得到6-溴-2,3,4,5-四氢-1H-吡啶并[4,3-b]吲哚盐酸盐,随后通过三氟乙酸和三乙基硅氢还原得到相应的消旋化合物6-溴-2,3,4,4a,5,9b-六氢-1H-吡啶并[4,3-b]吲哚盐酸盐,接着通过(S)-(+)-扁桃酸拆分得到手性的(4aS,9bR)-6-溴-2,3,4,4a,5,9b-六氢-1H-吡啶并[4,3-b]吲哚(S)-(+)-扁桃酸盐。然后与氯甲酸乙酯反应得到相应的(4aS,9bR)-6-溴-2,3,4,4a,5,9b-六氢-2H-吡啶并[4,3-b]吲哚-2-羧酸乙酯,最后与2-氯-N-甲基乙胺盐酸盐反应,通过CuI偶联得到卢美哌隆关键中间体。(Scheme 3)
专利(WO 2020112941 A)的技术路线如Scheme 4所示。该路线与J.Med.Chem.路线的不同之处在于四氢吡啶环上N保护基换成苄氧羰基,使用钯催化C-N偶联构建四环结构,然后再钯碳催化氢化还原和脱苄氧羰基后得到消旋体,再与L-(-)-对甲基二苯甲酰酒石酸成盐拆分、游离,得到光学纯的化合物。该路线使用昂贵的钯催化偶联,拆分步骤过于靠后,造成物料的浪费。
专利(CN 112062767 A)报道的技术路线如Scheme 5所示,以邻溴六氢-γ-咔唑为底物,经Ru/JosiphosSL-J505-1不对称氢化,酒石酸结晶得到手性的邻溴八氢-γ-咔唑,经Boc2O保护,N-烷基化反应,CuI催化Ullmann偶联,酰胺还原,脱Boc反应,还原胺化,格氏加成反应得到卢美哌隆。该技术路线关键步骤利用不对称氢化、酒石酸结晶合成手性的邻溴八氢-γ-咔唑,使用的手性配体JosiphosSL-J505-1价格昂贵,且不对称催化转化数(S/C=1000)不高,工业应用价值有限。
由此可见,现有的卢美哌隆中间体的制备方法存在成本高昂、工艺复杂、环境友好性差以及收率低的问题。
