The regioselectivity (r.s.) and enantiospecificity (e.s.) of the substitution reactions of secondary propargylic alcohol derivatives using reagents derived from ArMgBr and Cu salts were studied. First, the picolinate, 3-methylpicolinate, and diethylphosph

Oxime-directed catalytic asymmetric hydroboration is diverted to catalytic asymmetric hydrogenation (CAH) upon the addition of a proton source, such as MeOH, or by running the reaction under a hydrogen atmosphere. A borane (e.g., pinacolborane) is require
Rhodium-catalyzed asymmetric conjugate addition of arylboroxines to borylalkenes: Asymmetric synthesis of β-arylalkylboranes

Asymmetric conjugate addition of arylboroxines to borylalkenes proceed in the presence of a chiral bisphosphine/rhodium complex as a catalyst to give chiral β-arylalkylboranes with high enantioselectivities (see scheme). [O]=H2O2/NaOH.
