In the present study, the structural characteristics that impart antibacterial activity to C16 alkynoic fatty acids (aFA) were further investigated. The syntheses of hexadecynoic acids (HDA) containing triple bonds at C‐3, C‐6, C‐8, C‐9, C‐10, and C‐12 were carried out in four steps and with an overall yield of 34–78%. In addition, HDA analogs containing a sulfur atom at either C‐4 or C‐5 were also
Abstractn‐Alkyn‐1‐ols show fragmentation patterns which are influenced by the length of the chain and by the relative positions of the hydroxyl group and triple bond, and which allow a localization of the site of unsaturation.

A general approach to the synthesis of 9(Z)-unsaturated acyclic insect pheromones from undec-10-enoic acid was developed. The method comprises the conversion of the acid into undec-10-enyl acetate, shortening of its carbon chain to afford dec-9-enyl acetate (via 11-acetoxyundecanoic acid), and a two-step transformation of the latter into the key intermediate, dec-9-yn-l-ol, by sequential bromination-dehydrobromination. The elimination of two HBr molecules from the dibromide is effectively performed using (BuOK)-O-t in the presence of dibenzo-18-crown-6 as the catalyst.
