Highly enantioselective conjugate addition of nitromethane to chalcones using bifunctional cinchona organocatalysts
摘要:
Cinchona alkaloid-derived chiral bifunctional thiourea organocatalysts were synthesized and applied in the Michael addition between nitromethane and chalcones with high ee and chemical yields.
