1-Nitroicosane as the Key Building Block for the First Synthesis of Triacontan-11-ol, A New Fatty Alcohol Isolated from<b>
<i>Argemone mexicana</i>
</b>
<b />
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.

The hydrogenolysis and dimerization of iodoalkanes were catalyzed by Pd in the presence of an appropriate reducing agent. Hydrazine was found to be effective for the coupling of 1-iodoeicosane to give tetracontane, C40H82, in a 74% yield. The yield of the coupling product decreased with the decrease of the number of the carbon atoms in the 1-iodoalkanes. Both alkylhydrazines and alkenes were shown

diastereoselectively introduce α-substituents to chiral β-hydroxy esters, however, the yields of reactions in which longer chain alkyl halides are used can be disappointing. To provide a more robust protocol for the alkylation of β-hydroxy esters, we prepared a variety of long-chain allylic iodides with the view that the greater reactivity of the allylic system would
