A total convergent synthesis of lipoxins A4 and B4 has been carried out via four optically pure α-hydroxy and α,β-dihydroxyaldehydes, obtained from D-isoascorbic acid as a single starting material. Connection by a six carbons unit uses Wittig-type reactions notably involving a stabilized arsonium ylide.

The totalsynthesis of lipoxins A4 and B4 (LXA4 and LXB4) as well as of their all-trans isomers is reported. A study concerning the final steps of deprotection of silyl ether, cyclic carbonate and ethyl ester assisted by a high-speed scanning UV spectrophotometer has been carried out.
