A novel 1,2-alkyl migration of [trialkyl(4-pyridyl)borates] was written by Ishikura, Minoru;Ohta, Tsukasa;Terashima, Masanao. And the article was included in Heterocycles in 1986.Quality Control of 4-Hexylpyridine This article mentions the following:
4-Alkylpyridines were prepared from trialkyl(4-pyridyl)borates via the 1,2-alkyl migration in the presence of Lewis acids or acylating agents. Trialkyl(4-pyridyl)borates also reacted with 3-indolylacetyl chloride to yield an unstable dieneamide and 4-alkylpyridine. In the experiment, the researchers used many compounds, for example, 4-Hexylpyridine (cas: 27876-24-0Quality Control of 4-Hexylpyridine).
4-Hexylpyridine (cas: 27876-24-0) belongs to pyridine derivatives. The pyridine ring occurs in many important compounds, including agrochemicals, pharmaceuticals, and vitamins. Pyridine derivatives are also useful as small-molecule α-helix mimetics that inhibit protein-protein interactions, as well as functionally selective GABA ligands.Quality Control of 4-Hexylpyridine
