In this work we describe the regio and stereoselective synthesis of (E)-3,3-diaryl and (E)-3-aryl-3-aryloxy allylamines and allylalcohols. The starting materials are the non-expensive commercially available cinnamyl alcohol and chloride. The bromination/dehydrobromination sequence furnished the (E)-3-bromo-3-phenylallyl amines and alcohol as single regioisomers and with high stereoselectivity (>98%). These vinyl bromides were used as substrates in cross-coupling reactions furnishing the arylated products with good to excellent yields and total E-configuration retention. With this protocol, we were able to produce regio and stereospecifically trisubstituted olefins and vinyl ethers by Suzuki cross-coupling and Ullmann vinylation.
