概要

• 論文の詳細を見る

• The behavior of several N-substituted-4-piperidones in methanol has been studied by ^<13>C nuclear magnetic resonance (NMR) spectroscopy. All the piperidones studied were found to be equilibrium with their hemiacetals in methanolic solutions. The features of N-acyl derivatives were different from those of N-alkyl derivatives and the differences could be accounted for by electronic factors. The chemical shifts of the acetals were also determined and a procedure for distinguishing between hemiacetal and acetal is proposed.
