General description

(2R,5R)-(+)-2-tert-Butyl-3-methyl-5-benzyl-4-imidazolidinone is a chiral imidazolidinone organocatalyst, developed by MacMillan and co-workers.

Application

Used in the 1,4-addition of electron-rich benzenes to unsaturated aldehydes, and the asymmetric hydride reduction of α,β-unsaturated aldehydes.

Features and Benefits

Advantages of MacMillan imidazolidinone organocatalysts:
  • Superior enantiocontrol in numerous transformations
  • High activities at low catalyst loadings
  • Extraordinary functional group tolerance
