A short and efficient one-pot synthesis of uracil derivatives with a high structural variability is described. The process is a multicomponent reaction based on a palladium-catalyzed carbonylation of α-chloroketones in the presence of primary amines and isocyanates. In most cases, when the formation of unsymmetrical N,N′-disubstituted uracil derivatives can occur, the methodology demonstrates to be
A novel and convenient strategy is described for the regioselective conversion of N,N′-disubstituted thioureas and 1,2-dielectrophiles into the highly biologically valuable 2-imino-thiazoline and 2-imino thiazolidine-4-one derivatives. The synthesis proceeds through a process with good yield promoted by an electrogenerated base (EGB) obtained with high current efficiency.
