An unusual thermodynamic preference of chiral N-arylsulfonyl cis-3-alkyl-2-vinylaziridines over their trans-isomers: palladium(0)-catalysed equilibration reactions
Abstract
Palladium (0)-catalysed reactions of N-alkylsulfonyl- or N-arylsulfonyl-3-alkyl-2-vinyfaziridines reveal that 2,3-cis-isomers are more stable than the corresponding 2,3-trans-isomers in accord with ab initio calculations.
