General description

The product is a cinchona-alkaloid-derived, bifunctional catalyst containing a thiourea group at position 9.

Application

N-[3,5-Bis(trifluoromethyl)phenyl]-N′-[(9R)-6′-methoxy-9-cinchonanyl]thiourea may be used to catalyze the formation of optically active Mannich adducts from stable N-carbamate amido sulfones via enantioselective Mannich reaction.
Highly enantioselective conjugate addition of nitromethane to chalcones using bifunctional cinchona organocatalysts

Features and Benefits

N-[3,5-Bis(trifluoromethyl)phenyl]-N′-[(9R)-6′-methoxy-9-cinchonanyl]thiourea as an organocatalyst has the following advantages over transition-metal catalysis:
  • Lower toxicity
  • Lower costs
  • Air and moisture stability for simple reaction setup

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.
