Catalyzed Asymmetric Induction of Planar Chirality: Palladium-Catalyzed InMizoroki—Heck Reaction of Prochiral (Arene)chromium Complex36- 082 tramolecular
es. — The reaction of prochiral substrate (I) proceeds smoothly in the presence of
(S)-BINOL-based P—N ligand (BIMEP) to give the chromium-complexed indene derivatives (II) or (III) in up to 73% optical purity. An analogous reaction with the homologue (IV) gives tetralin (V) with decreased enantioselectivity. Additionally, this method can be directly used in a reaction cascade of (I) with Suzuki—Miyaura coupling as
is demonstrated for complexes (VII). — (KAMIKAWA, K.; HARADA, K.;
