synthesis of pyrimidinederivatives has been developed. It involves a [3 + 2 + 1] three-component annulation of amidines, ketones, and one carbon source. N,N-Dimethylaminoethanol is oxidized through C(sp3)–H activation to provide the carbon donor. One C–C and two C–N bonds are formed during the oxidative annulation process. The reaction shows good tolerance to many important functional groups in air, making

An efficient Au-catalyzed domino intramolecular cyclization reaction has been developed for the construction of pyrimidine derivatives from ynals and amidines at room temperature for 3 h. This transformation provides a new method for the formation of C-C and C-N bonds via intramolecular cyclization. (C) 2015 Published by Elsevier B.V.
