Abstract: | Reformatsky reagents generated from alkyl esters of bromoacetic, -bromopropionic, -bromobutyric, and -bromoisobutyric acids react with alkyl esters of 6,8-dibromo-2-oxochromene-3-carboxylic acid to form alkyl esters of 6,8-dibromo-4-(1-alkoxycarbonylalkyl)-2-oxochromane-3-carboxylic acid. |
