Enantioselective Conjugate Addition of Malononitriles to Enynes: A Stereodivergent Approach to Chiral Allenes

Quinine‐catalyzed enantioselective conjugate addition of malononitrile derivatives to enynes enables stereodivergent synthesis of trisubstituted chiral allenes. The reaction proceeds under mild conditions with good to excellent yields and high enantiomeric purities for both diast...

Enantioselective Synthesis of Spiropyrrolidines by Synergistic Catalysis

Abstract A stereoselective methodology for the synthesis of highly substituted spiropyrrolidines via synergistic catalysis was developed. The transformation is based on a cooperative catalytic system combining chiral phosphoric acid (CPA) catalysis with achiral palladium catalysi...
