Description

一种由二氧化碳制备ε-,ζ-,η-氰基羧酸的方法A method for preparing ε-, ζ-, η-cyanocarboxylic acids from carbon dioxide

技术领域technical field

本发明涉及医药、有机化工及精细化工领域,特别涉及一种铱、4CzIPN或钌催化的,以二氧化碳、烯烃、环酮肟为原料,以DIPEA或者三乙胺为还原剂,DMSO为溶剂,简单高效的合成ε-,ζ-,η-氰基羧酸化合物的方法。The present invention relates to the fields of medicine, organic chemical industry and fine chemical industry, in particular to a simple and efficient method for synthesizing ε-, ζ-, η-cyanocarboxylic acid compounds catalyzed by iridium, 4CzIPN or ruthenium, using carbon dioxide, olefins and cyclic ketone oxime as raw materials, using DIPEA or triethylamine as reducing agent, and DMSO as solvent.

背景技术Background technique

氰基羧酸是一类重要的具有生物活性的化合物,也是构建维生素B6、咖啡因、叶酸等药物分子的重要中间体(参见:(a)Oliver,L.;Jens-Uwe,R.;Hilke-Marie,L.;Paul,H.;Constanze,M.Preparation cyano carboxylic acid esters,EP 2455365A1,20120523;(b)Michael Paul,B.;John Wing,W.Biocatalytic preparation of 1-cyanocyclohexaneacetic,WO 2004111256A1,20041223.)。此外,其结构中的氰基可以水解成羧基,所得的脂肪族二羧酸化合物,在高分子聚合反应中有着广泛的应用,是合成聚酰胺、聚酯的重要单体,因此,该类化合物的有效合成具有较强的应用价值(参见:Ren,W.;Chu,J.;Sun,F.;Shi,Y.Org.Lett.2019,21,5967-5970;(b)Yang,J.;Liu,J.;Ge,Y.;Huang,W.;Neumann,H.;Jackstell,R.;Beller,M.Angew.Chem.Int.Ed.2020,59,20394–20398.)。该类化合物的经典合成方法是利用卤代羧酸与氰化钠或者氢氰酸的亲核取代反应制备得到,然而该法中需要用到剧毒的氰化钠或者氢氰酸,给实际操作带来了极大的麻烦;此外,通过二腈类化合物的单氰基水解反应,也是制备氰基羧酸的一类重要方法,然而化合物中两个氰基具有相似的反应活性,如何控制反应条件,保证只有一个氰基被水解,是一项具有挑战性的工作(参见:Zhu,D.;MukherJee,C.;Biehl,E.R.;Hua,L.Adv.Synth.Catal.2007,349,1667–1670.)。Cyanocarboxylic acids are a class of important biologically active compounds, and are also important intermediates for the construction of vitamin B6, caffeine, folic acid and other drug molecules (see: (a) Oliver, L.; Jens-Uwe, R.; Hilke-Marie, L.; Paul, H.; Constanze, M. Preparation cyano carboxylic acid esters, EP 2455365A1, 20120523; (b) Michael Paul , B.; John Wing, W. Biocatalytic preparation of 1-cyanocyclohexaneacetic, WO 2004111256A1, 20041223.). In addition, the cyano group in its structure can be hydrolyzed into a carboxyl group, and the resulting aliphatic dicarboxylic acid compound is widely used in polymer polymerization reactions and is an important monomer for the synthesis of polyamides and polyesters. Therefore, the effective synthesis of such compounds has strong application value (see: Ren, W.; Chu, J.; Sun, F.; Shi, Y. Org. Lett. 2019, 21, 5967-5970; (b) Yang, J.; Liu, J.; Ge, Y.; Huang, W.; Neumann, H.; Jackstell, R.; Beller, M. Angew. Chem. Int. Ed. 2020, 59, 20394–20398.). The classic synthetic method of this kind of compound is to utilize the nucleophilic substitution reaction of halogenated carboxylic acid and sodium cyanide or hydrocyanic acid to prepare, yet need to use highly toxic sodium cyanide or hydrocyanic acid in this method, has brought great trouble to practical operation; In addition, through the single cyano group hydrolysis reaction of dinitrile compound, also is a class of important method of preparing cyano carboxylic acid, but two cyano groups have similar reactivity in the compound, how to control reaction conditions, guarantees that only one cyano group is hydrolyzed, is a challenging work (see: Zhu, D .; MukherJee, C.; Biehl, E.R.; Hua, L. Adv. Synth. Catal. 2007, 349, 1667–1670.).

近期,于达刚教授报道了通过环酮肟酯与二氧化碳的开环羧基化反应,可以得到一系列的氰基羧酸,然而该反应只限于2-芳基取代的环酮肟酯,底物适用范围较窄,且底物的合成难度较大(参见:Jiang,Y.-X.;Chen,L.;Ran,C.-K.;Song,L.;Zhang,W.;Liao,L.-L.;Yu,D.-G.ChemSusChem 2020,13,6312–6317.)。进一步发展通过简单易得的原料,反应条件温和的方法,实现不同碳链长度的氰基羧酸类化合物的快速构建,具有较高的研究价值。Recently, Professor Yu Dagang reported that a series of cyanocarboxylic acids can be obtained through the ring-opening carboxylation of cyclic ketoxime esters with carbon dioxide. However, this reaction is limited to 2-aryl substituted cyclic ketoxime esters, and the scope of substrate application is narrow, and the synthesis of substrates is difficult (see: Jiang, Y.-X.; Chen, L.; Ran, C.-K.; Song, L.; Zhang, W.; Liao, L.-L.; Yu, D.-G. ChemSus Chem 2020, 13, 6312–6317.). It is of high research value to further develop the method of using simple and easy-to-obtain raw materials and mild reaction conditions to realize the rapid construction of cyanocarboxylic acid compounds with different carbon chain lengths.

The reaction vessel was evacuated to about -0.1 MPa (last 30 seconds each) and backfilled with CO2 (1 atm) in three installments. Then, the Schlenk tube was stirred at room temperature under 2 × 3W blue LED illumination for 12 h. After that, MeI (0.8 mmol) was added to the reaction mixture, the reaction mixture was stirred at 50 °C for about 1 hour, then the reaction mixture was diluted with brine and extracted (EA) with ethyl acetate at least 6 times (2 mL×6). Then, the combined organic layers were dried over anhydrous Na 2 SO 4 and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel (PE/EA 5/1) to give the desired product in 51% yield.核磁数据: 1 H NMR(400MHz,CDCl 3 )δ7.34–7.28(m,10H),3.71(s,3H),2.43–2.38(m,2H),2.27(t,J=7.2Hz,2H),1.68-1.60(m,2H),1.26-1.19(m,2H). 13 C NMR(101MHz,CDCl 3 )δ174.5,142.4,128.7,127.9,126.9,119.5,60.1,52.4,37.3,29.6,25.7,24.5,16.8.质谱数据:MS(EI):307.2(M + )。
