α-Isocupreine, an enantiocomplementary catalyst of ß-isocupreidine.

Complementary chemistry! α-Isocupreine (-ICPN) was synthesized for the first time in one step from quinine by treatment with CF3SO3H (see scheme). This compound serves as an enantiocomplementary catalyst to ß-isocupreidine (ß-ICD) in the Morita­Baylis­Hillman reaction.
