| Abstract: | An initial study of the side-chain unsubstituted 2'-hydroxyacrylophenone system shows it to have a considerably greater propensity for intermolecular addition than the comparable 2'-hydroxychalcone system, readily undergoing base-catalysed addition of, for example, alcohol and thereby diverting typical chalcone reactions requiring alcoholic alkali. 2'-Acetoxyacrylophenone dibromides and bromoalkoxides cyclize with base to chromone epoxides as do 2'-acetoxy--bromoacrylophenones in alcoholic alkali. |
