Synthesis of (2E,4E)-dienals by double formyl-olefination with an arsonium salt and its application in the syntheses of lipoxygenase metabolites of arachidonic acid
A new facile route to (2E,4E)-dienals by a double formyl-olefination with arsoniumsalts has been developed. By this method and with other arsonium reagents in the key step some lipoxygenase metabolites of arachidonic acid, lipoxin A4 and B4 and leukotriene B4, have been synthesized.
