Synthesis route :
Aldehyde C-14 is actually a lactone, in other words, a cyclic ester. Its synthesis is carried out by a free-radical addition of 1-octanol to acrylic acid. It can also be prepared by a reaction between 10-undecylenic aldehyde and sulfuric acid.
Synthesis precursor :
Aldehyde C-14 is not a precursor for the synthesis of another compound of olfactory interest.
Isomerism :
Aldehyde C-14 has two isomers (R) and (S) as it contains an asymmetric carbon. The (R) enantiomer has a peachy smell while the (S) enantiomer has a more aldehydic smell. The racemic mixture of the two enantiomers is the compound that is used in perfumery.
Citronellyl Formate is a constitutional isomer of Aldehyde C-14. Its smell is more reminiscent of pear and rose than peach.
