AI Article Synopsis

  • The study demonstrates the effectiveness of air-stable palladium complexes in catalyzing the one-pot asymmetric reductive amination of carbonyl compounds.
  • These complexes include [(R)-BINAP]PdBr2, [(S)-BINAP]PdBr2, [(R)-Tol-BINAP]PdBr2, and [(S,S)-CHIRAPHOS]PdBr2.
  • The process yields chiral amines with high yields and excellent enantioselectivity, achieving values close to 99% ee.

Article Abstract

The application of air stable preformed [(R)-BINAP]PdBr2, [(S)-BINAP]PdBr2, [(R)-Tol-BINAP]PdBr2, and [(S,S)-CHIRAPHOS]PdBr2 complexes in the one-pot asymmetric reductive amination of various carbonyl compounds, leading to chiral amines in very good yields with high enantioselectivities (<99% ee), is reported.
