  A Thermodynamic Preference of Chiral N-Methanesulfonyl and N-Arenesulfonyl 2,3-cis-3-Alkyl-2-Vinylaziridines over Their 2,3-Trans-Isomers:  Useful Palladium(0)-Catalyzed Equilibration Reactions for the Synthesis of (E)-Alkene Dipeptide Isosteres

  摘要：

  Palladium(0)-catalyzed reactions of N-methanesulfonyl- or N-(arenesulfonyl)-3-alkyl-2-vinylaziridines reveal that 2,3-cis-isomers are more stable than the corresponding 2,3-trans-isomers in accord with ab initio calculations. A highly stereoselective synthetic route to (E)-alkene dipeptide isosteres having desired stereochemistries from 2,3-cis-3-isobutyl-2-vinylaziridine by the use of organocopper chemistry is also presented.

  A convenient method for the synthesis of synthetically useful chiral 2-vinylaziridines from natural α-amino acids is described. Satisfactory 2,3-cis-selectivities are obtained by exposure of methyl carbonates of various allylic alcohols bearing an N-protected amino group to a catalytic amount of tetrakis(triphenylphosphine)palladium(>0>), Pd(PPh3)4, in aprotic solvents such as THF. Base-promoted aziridination of mesylates of various N-protected amino allylic alcohols followed by Pd(PPh3)4 catalyzed isomerization for the 2,3-cis-selective synthesis of vinylaziridines is also presented.
