A practical synthesis of chiral N-arylsulfonyl-cis-γ,δ-epimino-(E)-α,β-enoates, key intermediates for the synthesis of (E)-alkene dipeptide isosteres via Pd(0)-catalyzed equilibrated reactions, has been successfully achieved by exposing N-arylsulfonyl-γ,δ

Regio- and stereo-selective synthesis of (E)-alkene dipeptide isosters has been successfully achieved by exposing both (E)- and (Z)-N-(4-methylphenyl)sulfonyl-γ,δ-epimino-α,β-enoates to organocopper reagents at -78 deg C for 30 min.
