Polyfunctional molecules, 1,5-enynes, have been achieved via a palladium(0)-catalyzed domino coupling reaction of (Z)-β-bromostyrenes with norbornenes in the presence of cesium carbonate and N,N-dimethylformamide. The process involves a double Heck-type procedure, two-fold C(sp2) H activation and formation of two carbon-carbon bonds. There are possibilities of diversified transformation for the domino coupling of (Z)-β-bromostyrenes with norbornenes, the procedure is successfully driven to 1,5-enynes via accurate adjustment of the reaction conditions.

(E)-β-Bromostyrene reacts with norbornene (1a) or dicyclopentadiene (1b) in the presence of Pd(OAc)2, K2CO3, and nBu4NBr in DMF to yield a mixture of the 2:1 coupling products 4 and 5, while (Z)-β-bromostyrene gives exclusively 5.Under ana

2,3-Disubstituted norbornanes were prepared by the palladium catalyzed reaction of a ternary system composed of organic halide, organotin compound, and norbornene.Aryl and vinyl bromides, and acyl chloride were good substrates, but benzyl and allyl chlorides were not.Vinyl, phenyl, ethynyl, and allyltin compounds were utilizable reagents.
ONE-POT PALLADIUM-CATALYZED SYNTHESIS OF 2,3-DISUBSTITUTED BICYCLOHEPTANES AND BICYCLOHEPT-5-ENES

, p. 4517 - 4520 (2007/10/02)
A new and highly stereoselective palladium-catalyzed synthesis is reported, based on two subsequent insertion of the bicycloheptene system into an aryl or vinylpalladium bond, formed in situ from aryl or vinyl bromides.
