Cyclocondensation of α-acylacetamidines with esters of 2-fluoro-5-nitrobenzoic and 4-chloro-2-methyl-5-pyrimidinecarboxylic acids
摘要:
The cyclocondensation of alpha-acylacetamidines with esters of 2-fluoro-5-nitrobenzoic and 4-chloro-2-methyl-5-pyrimidinecarboxylic acids leads to condensed azines. The reaction proceeds chemoselectively such that the alpha-carbon atom of the amidine replaces the halogen atom in the aromatic ring, while the amino group reacts with the ester group.
