Dimerization of N-(pyrid-2-YL)- and N-(5-methylpyrid-2-YL) cyanoacetamides by the action of butylthiodibutylborane
摘要:
The reaction of N-(pyrid-2-yl) and N-(5-methylpyrid-2-yl) cyanoacetamides with butylthiodibutylborane in a 2:3 ratio leads to the formation of trinuclear complex boron compounds, the alcoholysis of which gave N,N'-di(pyrid-2-yl) 3-amino-2-cyanopent-2-ene-1,5-diamides. The latter are dimers of the starting cyanamides, which are capable of acting as hexadentate chelating agents.
Synthesis of N-(2-pyridyl)cyanoacetamides and 4-amino-2H-pyrido-[1,2-a]pyrimidin-2-ones from ethyl cyanoacetate and 2-aminopyridine
摘要:
The reaction of 2-aminopyridine and 2-aminopicolines with ethyl cyanoacetate under high pressures results in the formation of 4-amino-4H-pyrido[1,2-a]pyrimidin-2-ones. Depending on the structure of the initial pyridine base, heating of a mixture of the above reagents under low vacuum gives either the same products or their isomeric N-(2-pyridyl)cyanoacetamideBARs. The mutual transformations of the synthesized isomers were studied; it was found that cyanoacetamides are readily cyclized by the action of an alcoholic solution of HCl into pyrido[1,2-a]pyrimidin-2-ones, while the latter, during sublimation or heating in DMSO, undergo opening of the pyrimidine ring.

New chelating ligands, N-(pyrid-2-yl)amides of 4,4,4-trichloro-3-amino-2-cyanocrotonic acid have been synthesized from N-(pyrid-2-yl)amides of cyanoacetic acid and CCl3CN. It has been demonstrated that by the action of butylthiodibutylborane they form binuclear boron chelate complexes. Analogous chelates have also been obtained from the N-(pyrid-2-yl)amides of acetoacetic and 4,4,4-trichloro-3-aminocrotonic acids.
