  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.

  Palladium(0)-catalyzed reactions of five sets of four stereoisomeric 4,5-epimino-N-(methanesulfonyl) or -N-(arylsulfonyl) 2-enoates reveal that 4,5-cis-(2E)-isomers are thermodynamically more stable than other isomers, in accord with calculations.

  Although reactions of 2,3-trans-N-arylsulfonyl-3-alkyl-2-alkenylaziridines with organocopper reagents give a mixture of two or three products, the corresponding 2,3-cis-isomers provide a highly efficient route to synthetically important nonracemic (E)-allylamines. It is also found that the reaction proceeds via the well-known anti-S(N)2' pathway.

  The palladium-catalyzed reduction of various N-arenesulfonylaziridines bearing alpha,beta-unsaturated ester groups with formic acid and the stereochemistry of the reaction products have been investigated in detail. In all cases examined, (Z)-alpha,beta-enoates, (E)-alpha,beta-enoates, and (E)-beta,gamma-enoates bearing amino functionality at the delta-position were obtained. The formation of these three reduction products was taken as an indication that palladium-catalyzed isomerization occurs prior to the reduction step. (C) 1997 Elsevier Science Ltd.
