The first synthesis of triacontan-11-ol, a new fatty alcohol isolated from Argemone mexicana, has been realized starting from the nitroaldol reaction of 1-nitroicosane with decanal. Dehydration of the obtained nitroalkanol gives a long-chain nitroalkene which is then reduced to the corresponding nitroalkane. Nef transformation of the latter produces a ketone that is easily reduced to the fatty alcohol 9 in 21% overall yield. Georg Thieme Verlag Stuttgart.
The fluid-mosaic model, homeoviscous adaptation, and ionic liquids: Dramatic lowering of the melting point by side-chain unsaturation

(Figure Presented) Defying conventional wisdom: Ionic liquids (ILs) with long, unsaturated alkyl appendages (see top structure) defy established trends that link long ion-bound alkyl groups to higher melting points. The new ILs are also less viscous than a saturated standard (see bottom structure) at the same temperature. These features parallel those that underpin homeoviscous adaptation in certain organisms and are indirectly supportive of a fluid-mosaiclike nanoscale character.
