Conformational properties of N-acetyl-N-methyl-α,β-dehydroalanine N’-methylamide*


The conformational properties of Ac-∆(Me)Ala-NHMe (N-acetyl-N-methyl-α,β-dehydroalanine N’methylamide), as the simplest model of N-methyl-α,β-dehydroamino acids, was examined with theoretical methods and in comparison with Ac-∆Ala-NHMe and Ac-∆Ala-NMe2. The N-terminal amide of the ∆(Me)Ala residue easily adopts the configuration cis and the torsion angles… (More)
