E. Popa et al., SYNTHESIS AND STRUCTURE STUDY CONCERNING SOME CHALCONES DERIVED FROM O-FORMIL-P-ALPHA-CUMYLPHENOL, Revista de chimie, 46(1), 1995, pp. 25-32
The paper describes the synthesis of some new chalcones obtained by th
e alkaline condensation of the o-formyl p-alpha-cumylphenol with some
arylmethylketones, as well as the study of their structure. The stereo
- selective caracter of the condensation was proved, the chalcones ob
tained having a s-cis-Z structure. This was shown by the fact that the
reaction of chalcones with phenylhydrazine does not produce the corre
sponding substitued Delta(2)-pyrazolines, but stops at the phenylhydra
zone phase.
