A very simple and efficient procedure for the synthesis of novel 2-hydroxy-4H-pyrimido(1,2-a]pyrimidin-4-ones is described. Title compounds were obtained from the room temperature reaction of 2-aminopyrimidine and its substituted derivatives with bis(2,4,6-trichlorophenyl) malonates. High product yields were observed under optimized conditions. Applicability and reactivity of a range of substituted
Es wird die Synthese von Vertretern der bisher unbekannten Isoxazolidin-3,5-dione durch Umsetzung von Hydroxylamin oder N-monosubstituierten Hydroxylaminen mit substituerten Malonsäurechloriden beschrieben. Eine Anzahl der neuen Verbindungen wirken im Tierexperiment antiphlogistisch.

The preparation of unsaturated secondary lactams via the palladium-catalyzed cyclization of O-phenyl hydroxamates onto a pendent alkene is reported. This method provides rapid access to a broad range of lactams that are widely useful building blocks in alkaloid synthesis. Mechanistic studies support an aza-Heck-type pathway.

日期:——
A number of organoselenium reagents are introduced as efficient initiators of ringclosures leading from unsaturated substrates to lactones, cyclicethers, cyclic thioethers, N-heterocycles and carbocycles. These cyclizations often proceed with high ring selectivity and stereoselectivity and are accompanied by the incorporation of the phenylseleno group (PhSe) into the final product. Methods are described
