A New Type of Chiral Sulfinamide Monophosphine Ligands: Stereodivergent Synthesis and Application in Enantioselective Gold(I)-Catalyzed Cycloaddition Reactions
A simple, newtype of chiralsulfinamidemonophosphines, the so‐called Ming‐Phos ligands, is reported; these ligands could be easily prepared from inexpensive and commercially available starting materials. The Ming‐Phos ligands performed well in the enantioselectivegold‐catalyzed cycloadditionreaction of 2‐(1‐alkynyl)‐alk‐2‐en‐1‐ones with nitrones. Both enantiomers of the products could be obtained
