Asymmetric alkylations using chiral auxiliaries are now important and general methods for asymmetric carbon-carbon bond formation.Chiral 2-imidazolidinone has been used to be a versatile auxiliary for asymmetric syntheses, exhibiting excellent levels of stereocontrol, greater stability, and recyclability.Soluble polymer supports allow expeditious transfer of solution-based synthetic protocols.
