Zinc enolates formed from 1-aryl-2-bromoalkanones react with methyl esters of substituted 2-oxochromene-3-carboxylic acids to give methyl esters of 6-bromo- or 6,8-dibromo-4-(2-aryl-2-oxo-1-R- ethyl)-2-oxochromane-3-carboxylic acids as mixtures of two diastereomers.

3-Aroyl-6-bromochromen-2-ones and 2-benzoylbenzo[f]chromen-3-one reacted with zinc enolates derived from 1-aryl-2-bromoalkanones and 1-aryl-2-bromo-2-phenylethanone to give, respectively, 4-(1-alkyl-2-aryl-2-oxoethyl)-3-aroyl-6-bromochroman-2-ones and 1-(2-aroyl-1-methyl-2-oxoethyl)-2-benzoyl-1,2-dihydrobenzo[f]chromen-3-ones as a single stereoisomer. Treatment with acetic anhydride of the intermediate product obtained from 3-benzoyl-6-bromochromen-2-one and [1-(4-chlorophenyl)-2-phenylethen-1-yloxy]-zinc(II) bromide resulted in the formation of 3-(1-acetoxy-1-phenylmethylidene)-6-bromo-4-[2-(4-chlorophenyl)-2-oxo-1-phenylethyl]chroman-2-one.
