Abstract
The reaction of 3,5-dimethyl-2-acetylfuran 2 with aromatic aldehydes a ffords chalcone analogues, which are converted by phenylhydrazine into the title compounds. Their structure was proved by means of H-1- and C-13-NMR spectra, mass spectra, as well as by roentgenography. The 13C -NMR assignments are substantiated by means of N-15-labelling.
