Abstract
- New Rh- and Pd-catalyzed regiodivergent and stereoselective intermolecular coupling reactions of imidazole derivatives with mono-substituted allenes are herein reported. Using a RhI/Josiphos system, perfect regioselectivities and high enantiomeric excess were obtained, while a PdII/dppf system gave linear products with high regioselectivities and high E/ Z selectivities. This method permits the atom economic synthesis of valuable branched and linear allylic imidazole derivatives. [ABSTRACT FROM AUTHOR]
