Synthesis of the bicyclic secondary amines via dimethylaminomethylene ketones from 3-pyrrolidone and 4-piperidone was written by Fukui, Hideto;Inoguchi, Kiyoshi;Nakano, Jun. And the article was included in Heterocycles in 2002.Recommanded Product: 5,6,7,8-Tetrahydropyrido[4,3-d]pyrimidine dihydrochloride The following contents are mentioned in the article:
The reaction of N-protected 3-pyrrolidone and 4-piperidone with N,N-dimethylformamide di-Me acetal gave the dimethylaminomethylene ketones, which reacted with several types of hydrazines, amidines, and guanidine to afford the secondary amines having fused ring system. This study involved multiple reactions and reactants, such as 5,6,7,8-Tetrahydropyrido[4,3-d]pyrimidine dihydrochloride (cas: 157327-49-6Recommanded Product: 5,6,7,8-Tetrahydropyrido[4,3-d]pyrimidine dihydrochloride).
5,6,7,8-Tetrahydropyrido[4,3-d]pyrimidine dihydrochloride (cas: 157327-49-6) belongs to pyrimidine derivatives. Pyrimidines are isomeric with two other forms of diazines: pyridazine, with the nitrogen atoms in the 1 and 2 positions; and pyrazine, with the nitrogen atoms in the 1 and 4 positions. We all know its importance to life – pyrimidine and purine bases are included in the structure of DNA and RNA.Recommanded Product: 5,6,7,8-Tetrahydropyrido[4,3-d]pyrimidine dihydrochloride
