Zhang, Zhongxing; Yin, Zhiwei; Kadow, John F.; Meanwell, Nicholas A.; Wang, Tao published the artcile< Azole-N-acetonitriles as carbonyl synthons: A one-pot preparation of heteroaryl amides from halides>, Reference of 5182-90-1, the main research area is heteroaryl amide preparation; halo heterocycle reaction azole acetonitrile oxidation amine displacement.
Azole-N-acetonitrile derivatives were utilized as synthons for an ambident carbonyl moiety via a strategy relying upon sequential base-mediated SNAr substitution of a 2-halo heterocycle, in situ oxidation, and amine displacement. This strategy allows prompt and efficient synthesis of N-containing heteroaryl amides directly from the corresponding halides via a one-pot process. E.g., reaction of 2-halo heterocycle I (R = Cl) with azole-N-acetonitrile derivative II, followed by reaction with Me2NH and oxidation with peracetic acid, gave 69% heteroaryl amide I (R = NMe2).
