Abstract
It has been found by 1H NMR spectroscopy that 2-acetoacetamido-4-methylpyridine (1) and 2-acetoacetamidopyrimidine (2) exist predominantly in keto forms in CDCl3 and DMSO. The amide group of 1 seems to be in a s-trans configuration in both solvents, whereas that of 2 is in a s-cis form in CDCl3, but predominantly in a s-trans isomer in DMSO at room temperature. Configurations of the enol forms are discussed.
