A novel pyrrolidine amide (MQ-A3) isolated from the tropical convolvulaceous species was synthesized in 5 steps by starting from commercially available 12-bromododecanol and (S)-2-methylbulylbromide. The absolute configuration of the natural product was confirmed by a comparison of the specific rotation values.
Synthesis of (S)-(+)-enantiomers of food-relevant (n-5)-monoenoic and saturated anteiso-fatty acids by a Wittig reaction

We developed an enantioselective synthesis for the food-relevant anteiso-fatty acids a15:0, a16:0, and a17:0. Different (carboxyalkyl)triphenylphosphonium bromide salts were coupled with (S)-3-methylpentanal in a Wittig reaction. Mixtures of the obtained cis-/trans-isomers were separated by Ag+-HPLC to give the novel cis-isomers of (S)-(+)-a15:1n-5, (S)-(+)-a16:1n-5, and (S)-(+)-a17:1n-5. Hydrogenation of the monoenoic products led to (S)-(+)-a15:0, (S)-(+)-a16:0, and (S)-(+)-a17:0, which are essential for the assessment of the bioactivity of tests with standards of anteiso-fatty acids.
Chiral discrimination of branched-chain fatty acids by reversed-phase HPLC after labeling with a chiral fluorescent conversion reagent

Anteiso fatty acids having 16 to 29 carbon atoms were labeled with the chiral fluorescent conversion reagents, (1R,2R)- and (1S,2S)-2-(2,3- anthracenedicarboximido)-cyclohexanol. The diastereomeric esters of anteiso acids having up to 20 carbon atoms were
Determination of the absolute configurations of the anteiso acid moieties of glycoglycerolipid S365A isolated from Corynebacterium aquaticum

, p. 1719 - 1722 (2007/10/03)
The absolute configurations of the two acid moieties, 12- methyltetradecanoate and 14-methylhexadecanoate, of glycoglycerolipid S365A isolated from Corynebacterium aquaticum were determined by an HPLC analysis after their conversion with the chiral fluore
