Abstract Various C 3 ‐symmetric molecules were prepared by trimerization of acetyl aromatic compounds and subsequently coupled with various boronic acids under Pd 0 catalysis conditions to generate oligoaryl/‐heteroaryl C 3 ‐symmetric molecules. Several furan‐ and thiophene‐containing star‐shaped molecules were prepared by the use of Suzuki−Miyaura cross‐coupling as a key step. Structural and conformational details were explored by semi‐empirical molecular orbital theory using the AM1 method. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
Room temperature multicomponent reactions (MCRs) are reported using Bi<sub>2</sub>O<sub>3</sub>, BiVO<sub>4</sub>, and Bi<sub>2</sub>WO<sub>6</sub> (nanoparticle) as heterogeneous catalysts. Among these, Bi<sub>2</sub>WO<sub>6</sub> (5 mol%) nanoparticles showed excellent reactivity for the synthesis of functionalized dihydropyridine, polyhydroquinoline, 4<italic>H</italic>-chromene and 2-amino-4<italic>H</italic>-benzo[<italic>b</italic>]pyran derivatives in aqueous medium.
