Description
Technical Field
The invention relates to an indoline derivative and a preparation method thereof, belonging to the technical field of organic synthesis.
Background
Heterocyclic compounds, especially nitrogen-containing heterocyclic compounds, are very important compounds which are generally important molecular skeletons of natural substances and pharmaceutical molecules. The nitrogen-containing heterocyclic compound has wide application in medicine and pesticide chemistry. For example, physostigmine is used primarily in the treatment of glaucoma, and can constrict the pupil and lower intraocular pressure. The clemastine is mainly used for the phenomena of skin redness and itching caused by various anaphylactic reactions, and rhinorrhea, sneezing, eye redness and itching and the like caused by pollen allergy and cold. Argatroban is an anticoagulant and is mainly used for ischemic cerebral infarction within 48 hours of attack and improvement of nervous symptoms (motor paralysis) of patients in acute stage. Prasugrel is mainly used for treating cardiovascular and cerebrovascular diseases such as heart failure, stroke, unstable angina pectoris and the like. In addition, the nitrogen-containing heterocycle is also applied to the aspects of metal catalytic materials and fuel sensitized solar cells due to the characteristics that the nitrogen-containing heterocycle is easy to carry out structural modification and is convenient for introducing various groups. Therefore, the formation of C-N bond to construct the nitrogen-containing heterocyclic compound skeleton is of crucial importance in synthetic chemistry. Transition metal catalyzed C-H bond functionalization has been an effective, versatile method of constructing complex molecules for the last few decades. The targeting, also called Ligand-Directed (Ligand-Directed) or complexation-Directed (Coordination-Directed), is that a molecule requiring C-H activation and a transition metal can form a relatively stable cyclic metal intermediate by virtue of the complexation between the Ligand and the transition metal through an existing group having Coordination ability in the molecule, so that a C-M bond is formed at an expected position, and a functionalization reaction further occurs. Among many reports, C — H bond activation with the aid of a directing group has attracted considerable attention due to its good selection and functional group tolerance.
At present, many synthetic methods for synthesizing indoline derivatives have been reported. In 2008, Yu project group first discovered a targeting group of trifluoroformamide, which can be applied to ortho-iodination of phenylethylamine to achieve selective functionalization of C — H bond. On this basis, they further succeeded in synthesizing indoline derivatives (Li, j. -j.; Mei, t. -s.; Yu, j. -q.angelw.chem.int.ed.2008, 47,6452.). After a while, the Yu topic group reported a breakthrough development. They use Ce (SO)4)2Or F+As strong oxidizing agents instead of copper salts[15]The phenethylamine protected by the trifluoroformamide is taken as a substrate to be directly synthesized in one stepIndoline derivatives are provided. However, 10 to 15 mol% of palladium (II) and a large amount of oxidizing agent (Mei, T. -S.; Wang, X.; Yu, J. -Q.J.Am.chem.Soc.2009,131,10806.) are required to achieve this conversion.
In 2011, Chen and Daugulis project groups reported picolinamide-directed palladium-catalyzed C (sp), respectively2) -H and C (sp)3) Intramolecular ammoniation reaction of-H, all using PhI (OAc)2As an oxidant, a series of azetidine and pyrroline derivatives ((a) He, G.; ZHao, Y.; Zhang, S.; Lu, C.; Chen, G.J.Am.Chem.Soc.2012,134,3.(b) Nadres, E.T.; Daugulis, O.J.Am.Chem.Soc.2012,134,7.) are synthesized through five-membered ring palladium transition states and six-membered ring palladium transition states respectively, so that C-N bonding of a challenging aliphatic amine substrate is realized. Subsequently, Chen subject group found that oxygen has a certain inhibitory effect on cyclization reaction of amine substrates (He, G.; Lu C.; Zhao, Y.; Nack, W.A.; Chen, G.Org.Lett.2012,14,2944.), and they succeeded in synthesizing nitrogen-containing heterocyclic derivatives by modifying experimental conditions using argon as a reaction atmosphere, and under the reaction conditions, the catalyst dosage is less and the temperature is lower.
2012, the Shi topic group Pd (OAc)2Is catalyst, PhI (OAc)2As an oxidant, 1,2, 3-triazole formamide is a guide group, and an intramolecular C-N bond forming reaction is realized (Ye, X.; He, Z.; Ahmed, T.; Weise, K.; Akhmedov, N.G.; Petersen, J.L.; Shi, X.Chem.Sci.2013,4,3712.). In 2013, the Ma project group uses 2-methoxyiminoacetamide as a positioning group to realize amination reaction of 2-esterphenethylamine derivatives (He, Y-P.; Zhang, C.; Fan, M.; Wu, Z.; Ma, D.org.Lett.2015,17,496.). In this system, when PhI (OAc) is used2When used as an oxidizing agent, the reaction is not good in yield and by-products of the acyl oxidation are also present.
In 2014, Shi subject group realized palladium-catalyzed ammoniation reactions of phenethylamines, amphetamines and aliphatic amines with oxamides as targeting groups, forming five-and six-membered heterocycles ((a) Wang, Q.; Han, J.; Wang, C.; Zhang, J.Y; Huang, Z.B.; Shi, D.Q.; Zhao, Y.S.Chem.Sci.2014,5,4962.(b) Han, J.; Liu, P.; Wang, C.; Wang, Q.; Zhang, J.Y; Zhao, Y.W.; Shi, D.Q.; Huang Z.B.; Zhao, Y.S.O.; Wang, Z.B.rg.lett.2014,16,5682.). Despite the many advantages of this method, PhI (OAc)2Expensive and not readily available, so that the reaction can still be improved, the invention utilizes cheap and easily available peroxide TBPB instead of expensive PhI (OAc)2As the oxidizing agent, also can well realize palladium catalyzed oxamide induced intramolecular C-N bond forming reaction, so as to synthesize the indoline derivative.
