资源简介:
A palladium-catalyzed highly enantioselective allylic alkylation of pyrroles and 4,7-dihydroindoles has been successfully developed with the use of chiral alkene-phosphine hybrid ligands to furnish the desired products in high yields with excellent ee’s. It is noteworthy that alkene–phosphine ligands are much more effective than some other types of chiral ligands in this catalytic system.
