two ketones is described. This reaction was catalyzed by magnesium bromide and carried out under solvent-free conditions. When the reaction was performed by using 3-substituted anilines and nonsymmetrically substituted ketones, principally a single product was found among the four expected regioisomers. A variety of anilines and ketones, including cyclic ketones, were evaluated providing a series of

constituted by a fibrate-based structure was recently reported by our group, whose synthesis started from isovanillin derivatives. In the interest of evaluating the bioisosteric effect of the vanillin-based isomers on their antihyperlipidemic activity, the present study focuses on the synthesis of 5-acyl-1-phenoxyacetic methyl esters 5a–c and their saturated side-chain 5-alkyl-1-phenoxyacetates 6a–c. Their
