Abstract

The synthesis of N-substituted 3-aminomethylene-derivatives of 2,4-chromandiones, 6-methyl-pyrandiones and 1,6-dimethyl-2,4-pyridinediones is described. Stereochemistry of the mentioned enaminoketones is studied,E andZ isomers can be observed and the hindered rotation of the C—N bond is investigated by1H-NMR-spectroscopy at variable temperatures.
