Abstract
The reaction of 5-ethoxyoxazole with Β-acetylacrylic acid and its ethyl ester is examined, and the most probable mechanism for the heterodiene synthesis with oxazoles is suggested on the basis of the experimental results and on the calculation of the π-electron densities for these molecules.
