HN:C(NH2)2 reacted with RCOCR1:CHR3[R = Me, Ph3R1 = H, Me; R2 = H, Me, Ph, or R1R2 = (CH2)9] to give the unstable dihydropyrimidinimines I, which dehydrogenated to give the corresponding 2-pyrimidinamines II. The unstable I[R = Ph, R1 = H, R2 = Me; R-R2 = Me; R = Me, R1R2 = (CH2)4] were isolated as the corresponding stable 1H-2-pyrimidinium and 1H-2-quinazolinium picrates, whereas I(R = R2 = Ph, R1 = H) was isolated as its hydrochloride. In the experiment, the researchers used many compounds, for example, 4,6-Diphenylpyrimidin-2-amine (cas: 40230-24-8Related Products of 40230-24-8).
4,6-Diphenylpyrimidin-2-amine (cas: 40230-24-8) belongs to pyrimidine derivatives. Heterocyclic compounds bearing the pyrimidine core are of tremendous interest as they constitute an important class of natural and synthetic compounds exhibiting diverse useful biological activities that hold attractive potential for clinical translation as therapeutic agents in alleviation of a myriad of diseases. We all know its importance to life – pyrimidine and purine bases are included in the structure of DNA and RNA.Related Products of 40230-24-8
