In summary, we have successfully synthesized two novel trans-substituted aromatic lactone analogues of Lipoxin A4 in a convergent manner with six steps in the longest linear sequence using simple transformations and affordable reagents in overall 12–13% yield. In the presence of strong acids, THF converts to a linear polymer called poly(tetramethylene ether) glycol (PTMEG), also known as polytetramethylene oxide (PTMO): This polymer is primarily used to make elastomeric polyurethane fibers like Spandex. The other main application of THF is as an industrial solvent for polyvinyl chloride (PVC) and in varnishes. It is an aprotic solvent with a dielectric constant of 7.6. It is a moderately polar solvent a… rostom nashed khalil
