Hegde, V. B. published the artcileA general and versatile synthesis of 2-alkyl-4-aminopyridines, Category: pyridine-derivatives, the publication is Tetrahedron Letters (2001), 42(10), 1847-1849, database is CAplus.
A versatile 2-step synthesis of 2-alkyl-4-pyridinamines from com. available cis-1-methoxy-1-buten-3-yne is described. Acylation of the alkyne followed by amination and cyclization in NH3 produced the desired substituted pyridines in high yield.
Tetrahedron Letters published new progress about 18437-58-6. 18437-58-6 belongs to pyridine-derivatives, auxiliary class Pyridine,Amine, name is 4-Amino-2-picoline, and the molecular formula is C6H8N2, Category: pyridine-derivatives.
