Oxidative Annulations Involving DMSO and Formamide: K2S2O8 Mediated Syntheses of Quinolines and Pyrimidines
Jadhav, Santosh D.,Singh, Anand
, p. 5673 - 5676 (2017)
An efficient strategy toward 4-arylquinolines and 4-arylpyrimidines from readily available precursors is described. Oxidative annulation promoted by K2S2O8 involving anilines, aryl ketones, and DMSO as a methine (=CH-) equivalent leads to 4-arylquinolines via a cascade that entails generation of a sulfenium ion, subsequent C-N and C-C bond formations, and cyclization. The application of this strategy to the activation of acetophenone-formamide conjugates toward the synthesis of 4-arylpyrimidines is also described.

We have developed a ZnCI2-catalyzed three-component coupling reaction involving a variety of functionalized enamines, triethyl orthoformate, and ammonium acetate, which leads to the production of 4,5-disubstituted pyrimidine derivatives in a single step. The procedure can be successfully applied to the efficient synthesis of mono- and disubstituted pyrimidine derivatives, using methyl ketone derivatives instead of enamines.
