- 論文の詳細を見る
Anisochrony of geminal methyls in alkylamines bearing a chiral center in the molecule is affected by complexation with crown ethers, which amplify the chemical shift non-equivalence in NMR. The resolved signal of <I>gem</I>-methyls in valine methyl ester were unequivocally assigned to <I>pro</I>-<I>R</I> and <I>pro</I>-<I>S</I> methyl groups respectively.
