A series of pyrimidine-2(1H)-one derivative were obtained by multi-component one-pot synthesis under microwave irradiation. Equimolar quantities of ethylacetoacetate, substituted benzaldehydes and urea undergo condensation followed by cyclizaton in presence of aqueous solution of sodium hydroxide to produce corresponding pyrimidine derivatives. With the help of microwave heating, there is clean reaction with shorter reaction time, environmental-friendly, improved yield as compared to conventional heating method. The structures of the newly synthesized compounds have been established on the basis of their IR, NMR spectral data. These compounds were screened for their anti-inflammatory activity. Some of them were found to possess significant activity as compared to standard drug.

Pyrimidin-2-yl sulfonates, as a reaction partner, can be easily prepared from inexpensive commercial materials and are efficiently cross-coupled with arylboronic acids and terminal alkynes by using Pd(OAc)2-catalyzed Suzuki and Sonogashira reactions. A wide array of C2-functionalized pyrimidines have been prepared in good to excellent yields. 2-Arylpyridines and 2-(oct-1-ynyl)pyridine were also synthesized. An efficient means to synthesize expanded pyrimidin-2-yl conjugated systems was developed by using Pd(OAc) 2-catalyzed cross-coupling reaction of pyrimidin/pyridin-2-yl sulfonates with arylboronic acids and terminal alkynes. Compared with 2-chloropyrimidines, pyrimidin-2-yl sulfonates can be easily prepared from inexpensive commercial materials and the reactions are more efficient. Copyright
