An operationally simple and efficient strategy employing palladium(0) catalyst to construct a wide range of thiobridged compounds through intramolecular Csp2(aryl)-Csp3(alkyl) cross-dehydrohalogenative coupling reaction has been reported. This methodology proceeds smoothly through six-membered palladacycles and serving as a keystone for the generation of C–C bond to furnish thiobridged derivative in

A convenient synthesis of substituted [1,2,4]-triazolo [1',2':1,2]pyrimido[6,5-b]-quinoline 4(a-i) from substituted 2-chloroquinoline-3-carbaldehyde 1(a-i) and 4H-1,2,4-triazol-3-amine 2 by using SiO 2 /K 2 CO 3 under microwave irradiation. This method affords the [1,2,4]-Triazolo [1',2': 1,2]pyrimido[6,5-b]-quinoline 4(a-i) under the influence of microwave irradiation in solvent-free conditions within

AbstractA new series of 2‐(p‐tolyloxy)‐3‐(5‐(pyridin‐4‐yl)‐1,3,4‐oxadiazol‐2‐yl)quinoline were synthesized from oxidative cyclization of N′‐((2‐(p‐tolyloxy)quinoline‐3‐yl)methylene)isonicotinohydrazide in DMSO/I2 at reflux condition for 3–4 h. The structures of the new compounds were confirmed by elemental analyses as well as IR, 1H‐NMR, and mass spectral data. All the synthesized compounds were screened for their antibacterial activities against various bacterial strains. Several of these compounds showed potential antibacterial activity. J.
