o-, m-, and p-(3,4-Dihydroxyalkenyl)benzaldehydes were selectively prepared via palladium-catalyzed Heck-type coupling reactions of o-, m-, and p-bromobenzaldehydes with 3,4-di(tert-butyldimethylsilyloxy)-1-alkene.The products were employed for the synthesis of lipoxin analogues, o-, m-, and p-3-hydroxyalkenyl-3,4-dihydroxyalkenylbenzenes.
