Description
Technical Field
The invention relates to the technical field of organic synthesis, in particular to a synthetic method of a nitrogen-containing heterocyclic compound and an intermediate thereof.
Background
The nitrogen-containing heterocyclic compound has a very important research position in the technical field of pharmaceutical chemistry. On the one hand, nitrogen-containing heterocyclic compounds are easy to structurally modify and convenient for introducing various functional groups, so that the nitrogen-containing heterocyclic compounds play an important role in drug design in the past decades. On the other hand, many drug lead molecules contain nitrogen-containing heterocyclic compound structures, and partial nitrogen-containing heterocyclic compounds are found to have certain biological activities, such as anticancer, antioxidation, antibiosis, antivirus, antifungal, anti-inflammatory and the like, and can be used as important synthetic building blocks of bioactive molecules.
The literature is concerned with the synthesis and evaluation of a series of 4-phenylpiperidines and 4-phenylpiperazines as ligands for the D2 receptor and the discovery of the dopaminergic stabiliser 4- [3- (methylsulfonyl) phenyl ] -1-propylpiperidine (Huntexil, Pridopidine, ACR 16). The synthetic route involving compound 11 is shown below:
the compound 4 and N-tert-butyloxycarbonyl-4-piperidone generate a compound 5 under the action of N-butyllithium; deprotecting and dehydrating the compound 5 under the action of trifluoroacetic acid to obtain a compound 6; reacting the compound 6 with methyl chloroformate under the action of triethylamine to obtain a compound 7; oxidizing the compound 7 with m-chloroperoxybenzoic acid to obtain a compound 8; catalytically hydrogenating the compound 8 to obtain a compound 9; deacetylating the compound 9 with hydrochloric acid to obtain a compound 10; the compound 10 reacts with a halide under the action of potassium carbonate to obtain a compound 11(4- [3- (methylsulfonyl) phenyl ] -1-propylpiperidine or 4- [3- (methylsulfonyl) phenyl ] -1-benzylpiperidine).
