A one-pot tandem palladium (II)-catalyzed aza-Claisen rearrangement and ring closing metathesis process has been developed for the efficient synthesis of cyclic allylic trichloroacetamides. The use of chiral Pd (II) catalysts such as (S)-COP-Cl during the rearrangement stage results in the preparation of these compounds in excellent yields and in high enantiomeric excess.
