Alkaloids containing the α-pyridone ring was written by Orjales, A.;Ribas, I.;Varela, A.. And the article was included in Anales de Quimica (1968-1979) in 1972.Recommanded Product: 13472-81-6 This article mentions the following:
Cytisine and anagyrine form dications in 6N HCl that have an aromatic character similar to that of 2-ethoxypyridine. Their dihydrobromides were isolated and arise from a amide-zwitterion equilibrium Halogenation of cytisine occurs in the 3- and 5-positions. PCl5 or POCl3 treatment of cytisine or its dichloro derivative gave 2-(4-chloromethyl-3-piperidyl)-3,5,6-trichloropyridine, which was oxidized with KMnO4 to 3,5,6-trichloropicolinic acid. In the experiment, the researchers used many compounds, for example, 3,5-Dibromo-2-hydroxypyridine (cas: 13472-81-6Recommanded Product: 13472-81-6).
3,5-Dibromo-2-hydroxypyridine (cas: 13472-81-6) belongs to pyridine derivatives. The ring atoms in the pyridine molecule are sp2-hybridized. The nitrogen is involved in the π-bonding aromatic system using its unhybridized p orbital. The lone pair is in an sp2 orbital, projecting outward from the ring in the same plane as the σ bonds. Several pyridine derivatives play important roles in biological systems. While its biosynthesis is not fully understood, nicotinic acid (vitamin B3) occurs in some bacteria, fungi, and mammals.Recommanded Product: 13472-81-6
