Cationic Palladium(II)-Catalyzed Highly Enantioselective Tandem Reactions of ortho-Boronate-Substituted Cinnamic Ketones and Internal Alkynes: A Convenient Synthesis of Optically Active Indenes
摘要:
Cationic palladium(II)-catalyzed tandem reactions of ortho-boronate-substituted cinnamic ketones and internal alkynes to yield optically active indenes were developed in high yields and good enantioselectivities.
