Fatty acids (C12-C18) and their omega- and (omega-1)-hydroxy derivatives, when converted to p-bromophenacyl (PBP) esters, can be completely separated from one another by high pressure liquid chromatography (HPLC) on a silicic acid column using 0.5% (v/v) isopropanol in n-hexane. In this system, fatt

✦ Synopsis
A solid-phase radioiodination technique for omega-iodophenyl fatty acids using ammonium sulfate is described. The radioiodinations are regioselective, high in yield (95%), short in reaction time (1 h) and capable of yielding high specific activity products although at lower yields. Purification is exceptionally simple: a single passage through an ion exchange column to remove unreacted I- is all that is required. Syntheses of several omega-iodophenyl fatty acids are also described.

A series of ω-trans-(bicyclopropyl)-substituted fatty acids 9 has been synthesized from bicyclopropylidene (5) starting by deprotonation with n-butyllithium. Electrophilic substitution of lithiobicyclopropylidene with THP-protected ω-iodoalkanols 6 gave the THP-protected (bicyclopropylidenyl)alkanol
A method for the synthesis of long chain fatty acids substituted at the to and to-1 positions has been developed. The key step is the isomerization of the triple bond of an alkyn-l-ol from an internal position in the chain to the free terminus with a new, convenient reagent, sodium aminopropylamide
