抄録

Chiral bis(α, α-diphenyl-2-pyrrolidinemethanol) carbonate (DPP₂·H₂CO₃) is a useful asymmetric auxiliary for the asymmetric borane reduction of prochiral ketones. Chiral DPP₂·H₂CO₃ is recoverable from the reaction and directly reusable for the reaction. The intermediate of KUR-1246, which we are developing as a new uterine relaxant, was synthesized using the methodology.
