and quinoxalines, respectively. This approach enables telescoping of the two steps into a single process. A simple and efficient one-pot protocol has been developed for the synthesis of thiazole derivatives from readily available starting materials. Tribromoisocyanuric acid was successfully used for α-monohalogenation of β-keto esters in aqueous medium, which in the presence of thiourea and DABCO produced

A difluoroalkene derivative which is sufficiently effective in controlling various pests even when used in a small dose and is highly safe for crops, natural enemies to the pests, and animals; and an intermediate for the derivative. The difluoroalkene derivative is represented by the general formula: [I] wherein L

A one-pot, three-componentprotocol for the synthesis of 2-aminothiazoles promoted by iodine from readily available starting materials such as b-diketones/b-ketoesters, arylamines, and NH4SCN has been developed. A wide range of arylamines was tolerated well to produce the expected polysubstituted 2-aminothiazoles in moderate to good yields. The characteristic features of this methodology include operational
