Description
技术领域technical field
本发明属于化学合成技术领域,具体涉及一种不对称催化合成手性1,4-二氢吡啶化合物的方法及其应用。The invention belongs to the technical field of chemical synthesis, and in particular relates to a method for asymmetric catalytic synthesis of chiral 1,4-dihydropyridine compounds and an application thereof.
背景技术Background technique
1,4-二氢吡啶化合物作为一种高效的钙离子通道阻滞剂而被广泛的用于心血管疾病的临床治疗,目前市面在售用于治疗高血压的1,4-二氢吡啶药物分子包括:非洛地平、氨氯地平、尼群地平、尼莫地平、尼索地平等,这类药物分子C-4位取代基的立体化学极大的影响该类结构的药理活性。因此,合成光学纯的1,4-二氢吡啶药物分子将有利于增强该类药物分子的临床治疗效果。目前,已公开了手性诱导、拆分以及不对称催化合成该类手性药物分子的策略。1,4-Dihydropyridine compounds are widely used in the clinical treatment of cardiovascular diseases as efficient calcium ion channel blockers. The 1,4-dihydropyridine drug molecules currently on the market for the treatment of hypertension include: felodipine, amlodipine, nitrendipine, nimodipine, nisoldipine, etc. The stereochemistry of the C-4 substituents of these drug molecules greatly affects the pharmacological activity of such structures. Therefore, the synthesis of optically pure 1,4-dihydropyridine drug molecules will be beneficial to enhance the clinical therapeutic effect of such drug molecules. Currently, strategies for chiral induction, resolution, and asymmetric catalytic synthesis of such chiral drug molecules have been published.
拆分:Split:
F.Dollé等人利用手性高效液相色谱(HPLC)实现了钙通道拮抗剂S11568的拆分反应,能分别以50%的收率得到两种构型的产物(Bioorg.Med.Chem.1997,5,749);尹永梅和郗日沫等人利用手性超临界流体色谱(SFC)实现了对1,4-二氢吡啶药物分子的手性拆分,通过对流速以及溶剂的调节,完成了对尼莫地平、氨氯地平、阿折地平、贝尼地平、西尼地平、尼索地平和非洛地平药物分子的拆分(J.ofSupercriticalFluids2016,107,129)。F.Dollé et al. realized the resolution reaction of calcium channel antagonist S11568 by chiral high-performance liquid chromatography (HPLC), and obtained two configurations of products with a yield of 50% (Bioorg.Med.Chem.1997,5,749); Yin Yongmei and Xi Rimo et al. used chiral supercritical fluid chromatography (SFC) to realize the chiral resolution of 1,4-dihydropyridine drug molecules. By adjusting the flow rate and solvent, the Separation of nimodipine, amlodipine, azeldipine, benidipine, cilnidipine, nisoldipine and felodipine drug molecules (J.ofSupercriticalFluids2016, 107, 129).
S.P.Sonawane等人利用(+)-L-酒石酸盐对氨氯地平药物分子进行拆分(Org.Process Res.Dev.2010,14,640)。在该反应中,以DMF/水(v/v=85:15)作为混合溶剂,(S)-氨氯地平与(+)-L-酒石酸盐以共结晶的形式析出,而(R)-氨氯地平则溶解在DMF/水混合溶液中。随后(S)-氨氯地平在异丙醇/水的混合溶剂中与苯磺酸在室温下即可转换成手性药物分子(S)-苯磺酸氨氯地平。S.P. Sonawane et al. used (+)-L-tartrate to resolve amlodipine drug molecules (Org. Process Res. Dev. 2010, 14, 640). In this reaction, DMF/water (v/v=85:15) was used as a mixed solvent, (S)-amlodipine and (+)-L-tartrate were precipitated in the form of co-crystals, while (R)-amlodipine was dissolved in the DMF/water mixed solution. Then (S)-amlodipine can be converted into a chiral drug molecule (S)-amlodipine besylate in a mixed solvent of isopropanol/water and benzenesulfonic acid at room temperature.
F.Rebolledo等人利用脂肪酶实现了1,4-二氢吡啶药物分子衍生物的动力学拆分(Tetrahedron2015,71,3976)。产物以34-51%的转换率得到58-98%ee对映选择性的水解产物。F. Rebolledo et al. used lipase to realize the kinetic resolution of 1,4-dihydropyridine drug molecule derivatives (Tetrahedron 2015, 71, 3976). The product was hydrolyzed with 58-98% ee enantioselectivity at 34-51% conversion.
手性诱导:Chiral induction:
S.Sundell课题组利用手性醇为原料,先后经历上保护基、酯化、加成脱水串联反应、去保护基、水解再酯化六步反应,以37%的收率得到手性felodipine药物分子(Tetrahedron Lett.1989,30,6423)。S. Sundell's research group used chiral alcohol as a raw material, and went through six steps of protecting group, esterification, addition and dehydration series reaction, removing protecting group, hydrolysis and re-esterification, and obtained chiral felodipine drug molecule with a yield of 37% (Tetrahedron Lett. 1989, 30, 6423).
H.-Y.Lee等人利用手性缩水甘油为起始原料,同样经历多步衍生,最终以22%的总收率得到(S)-felodipine(Tetrahedron2011,67,10222)。H.-Y.Lee et al. used chiral glycidol as a starting material, also underwent multi-step derivatization, and finally obtained (S)-felodipine with a total yield of 22% (Tetrahedron2011, 67, 10222).
不对称催化:Asymmetric Catalysis:
龚流柱等人利用手性联萘磷酸为催化剂、苯甲腈为溶剂、在50℃下反应24h,以31–93%的收率以及66–98%ee的对映选择性得到一系列手性1,4-二氢吡啶化合物(Angew.Chem.Int.Ed.2008,47,2458)。然而该类1,4-二氢吡啶产物难以转换成3,5-二羧酸酯基取代的手性1,4-二氢吡啶药物分子。Gong Liuzhu et al. used chiral binaphthyl phosphoric acid as a catalyst, benzonitrile as a solvent, and reacted at 50°C for 24 hours to obtain a series of chiral 1,4-dihydropyridine compounds with a yield of 31–93% and an enantioselectivity of 66–98% ee (Angew.Chem.Int.Ed.2008, 47, 2458). However, such 1,4-dihydropyridine products are difficult to convert into chiral 1,4-dihydropyridine drug molecules substituted with 3,5-dicarboxylate groups.
C.Bressy,X.Bugaut以及J.Rodriguez等人利用硫脲衍生物为手性有机小分子催化剂,二氯甲烷为反应溶剂,在37℃下反应24h,最终以25–71%的收率以及58–96%ee的对映选择性得到手性1,4-二氢吡啶化合物,该化合物结构同样难以转换为3,5-二羧酸酯取代的手性1,4-二氢吡啶药物分子(Angew.Chem.Int.Ed.2016,55,1401)。在氧化剂的作用下,该类1,4-二氢吡啶结构被氧化为吡啶,实现中心手性到轴手性的转变。C.Bressy, X.Bugaut and J.Rodriguez et al. used thiourea derivatives as chiral organic small molecule catalysts, dichloromethane as the reaction solvent, and reacted at 37°C for 24 hours, and finally obtained chiral 1,4-dihydropyridine compounds with a yield of 25–71% and an enantioselectivity of 58–96%ee. .Int.Ed.2016,55,1401). Under the action of an oxidizing agent, the 1,4-dihydropyridine structure is oxidized to pyridine, realizing the transformation from central chirality to axial chirality.
吴建一课题组利用金鸡纳碱衍生的手性小分子催化剂实现了尼群地平分子的不对称构建(AdvancedMaterialsResearch,2012,518-523,3943)。由于产物手性中心两端取代基分别为区分度较小的甲酯以及乙酯,因此该产物的手性控制较差,只能以41%ee的对映选择性得到尼群地平,且与该产物结构类似的其它1,4-二氢吡啶药物家族的不对称合成并未有涉及。Wu Jianyi's research group used cinchona base-derived chiral small molecule catalysts to realize the asymmetric construction of nitrendipine molecules (Advanced Materials Research, 2012, 518-523, 3943). Since the substituents at both ends of the chiral center of the product are methyl ester and ethyl ester with less discrimination, the chiral control of this product is poor, and nitrendipine can only be obtained with an enantioselectivity of 41% ee, and the asymmetric synthesis of other 1,4-dihydropyridine drug families similar to the product structure has not been involved.
综上所述,目前关于直接合成手性1,4-二氢吡啶药物分子及其衍生物的策略主要依靠拆分以及手性诱导。然而拆分最高只能做到50%的收率,原子经济性差;而手性诱导则需要提前制备底物,步骤冗长,收率较低,原子经济性差。虽然目前有一些小分子催化剂能够实现1,4-二氢吡啶化合物的不对称构建,并且有不错的手性控制,然而该类1,4-二氢吡啶化合物结构特殊,难以转换为真正的手性1,4-二氢吡啶药物分子。关于催化不对称合成手性1,4-二氢吡啶药物分子只有一例报道,但是手性控制较差,且只局限于尼群地平药物分子的合成。因此,有必要发展一种简单、高效、环境友好、底物普适性好的合成手性1,4-二氢吡啶化合物及其药物分子的方法。In summary, the current strategies for the direct synthesis of chiral 1,4-dihydropyridine drug molecules and their derivatives mainly rely on resolution and chiral induction. However, resolution can only achieve a maximum yield of 50%, which is poor in atom economy; while chiral induction needs to prepare substrates in advance, the steps are tedious, the yield is low, and atom economy is poor. Although there are currently some small molecule catalysts that can realize the asymmetric construction of 1,4-dihydropyridine compounds and have good chiral control, such 1,4-dihydropyridine compounds have special structures and are difficult to convert into real chiral 1,4-dihydropyridine drug molecules. There is only one report on the catalytic asymmetric synthesis of chiral 1,4-dihydropyridine drug molecules, but the chiral control is poor, and it is limited to the synthesis of nitrendipine drug molecules. Therefore, it is necessary to develop a method for synthesizing chiral 1,4-dihydropyridine compounds and their drug molecules that is simple, efficient, environmentally friendly and has good substrate universality.
