Palladium-catalyzed coupling reactions of bromobenzaldehydes with 3,4-di(tert-butyldimethylsilyloxy)-1-alkene to (3,4-dihydroxyalkenyl)benzaldehydes in the synthesis of lipoxin analogues
摘要:
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. (C) 1998 Elsevier Science Ltd. All rights reserved.
