A useful and effective rhodium catalyst system - [RhCl(PPh 3)3/DPPF] - for the Suzuki-Miyaura cross-coupling of activated alkenyl tosylates is described. The results not only represent the first examples of the rhodium-catalyzed Suzuki-Miyaura coupling of activated alkenyl tosylates with arylboronic acids under mild conditions, but also provide an efficient route for the synthesis of some natural product-like compounds, such as furan-2(5H)-one, coumarin, pyrone, and quinolin-2(1H)-one derivatives.

Coumarins from free ortho -hydroxy cinnamates by Heck-Matsuda arylations: A scalable total synthesis of (R)-tolterodine

supporting information, p. 6036 - 6039 (2013/02/23)
Free ortho-hydroxy cinnamate ester derivatives are evaluated in the synthesis of structurally diverse 4-aryl-coumarins via a tandem Heck-Matsuda cyclization reaction. Free phenolic groups were considered incompatible with such a reaction, which usually provide the corresponding diazo dyes. A concise and scalable route employing a ligand-free, Pd-catalyzed Heck-Matsuda arylation under aerobic conditions for the preparation of (R)-Tolterodine in high overall yield and ee is also presented.
Palladium-catalyzed synthesis of 4-arylcoumarins using triarylbismuth compounds as atom-Efficient multicoupling organometallic nucleophiles
Rao, Maddali L. N.,Venkatesh, Varadhachari,Jadhav, Deepak N.
experimental part, p. 3945 - 3955 (2010/09/05)
Triarylbismuth compounds have been cross-coupled as atomefficient multicoupling organometallic nucleophiles with. 4bromo- and 4- (trifluoromethylsulfonyloxy)coumarins under palladium catalysis conditions. These reactions afforded an array of 4-arylcoumari
