, p. 2697 - 2703 (2005)
A one-pot procedure for the direct coupling of 1-aryl-2- trimethylsilylacetylenes with aryl halides to give diaryl acetylenes is reported. The procedure does not involve the use of copper(I) iodide. Improvement in reaction yields has been obtained by replacing conventional oil bath heating with the use of microwave dielectric heating.

An asymmetric cobalt-catalyzed hydroboration/cyclization of 1,7-enynes to synthesize chiral six-membered N-heterocyclic compounds was developed. A variety of aniline-tethered 1,7-enynes react with pinacolborane to afford the corresponding chiral boryl-fun
Sequential hydration-condensation-double cyclization of pyridine-substituted 2-alkynylanilines: An efficient approach to quinoline-based heterocycles
Peng, Lijie,Wang, Honggen,Peng, Changlan,Ding, Ke,Zhu, Qiang

An environmentally benign and atom-economical process to construct a unique quinoline-based tetracyclic scaffold, through sequential hydration- condensation-double cyclization reactions, has been described. The reaction starts with readily available pyrid
