Asymmetric One-Pot Sequential Mannich/Hydroamination Reaction by Organo- and Gold Catalysts: Synthesis of Spiro[pyrrolidin-3,2′-oxindole] Derivatives
摘要:
An asymmetric organo- and gold-catalyzed one-pot sequential Mannich/hydroamination reaction has been developed. Using this protocol, spiro[pyrrolidin-3,2'-oxindole] derivatives were synthesized in good yields (up to 91%) and excellent enantioselectivities (up to 97% ee).
