Novel dienedicarboxylic acids with hydrocarbon chains of various lengt
hs (C-17:2, C-19:2, and C-20:2) were synthesized via the corresponding
diynedioic acids. These intermediates were in turn obtained by the cr
oss-coupling reaction of terminal acetylenic synthones with propargyl
bromides under copper catalysis.
