Relevant academic research and scientific papers

TOTAL SYNTHESIS OF LIPOXINS A4 AND B4 FROM D-ISOASCORBIC ACID

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 reaction

SYNTHESIS OF 5S-HYDROXY-14,15 LTA4 A BIOGENIC PRECURSOR TO THE LIPOXINS

A synthesis of 5S-hydroxy-14,15-LTA4 10 an intermediate in the biosynthesis of the lipoxins is described.

TOTAL SYNTHESIS OF LIPOXIN B: ASSIGNMENT OF STEREOCHEMISTRY

Four isomers of lipoxin B were synthesized using carbohydrate precursors.An authentic sample of lipoxin B (from human leukocytes) was found to be a mixture of all-trans isomers 1a and 1c.
