N-Heterocyclic carbene-catalyzed annulation of ynals with amidines: access to 1,2,6-trisubstituted pyrimidin-4-ones

A thiazolium-catalyzed annulation of ynals and amidines has been reported to construct pyrimidin-4-ones.

Palladium-catalyzed β-selective C(sp2)–H carboxamidation of enamides by isocyanide insertion: synthesis of N-acyl enamine amides

An efficient synthesis of N-acyl enamine amides via palladium-catalyzed alkene C–H activation and isocyanide insertion has been developed.

Xanthate based radical cascade toward multicomponent formation of pyrrolopyrimidines

A short sequential synthesis of pyrrolidino- pyridines and pyrimidines illustrates the potential of combining Ugi-Smiles couplings with radical tin-free processes.
