Abstract A simple regio-and stereoselective synthesis of unsaturated analogues of the plant growth stimulator 1-triacontanol from ω-alkyn-1-ols is reported. Starting from the easily accessible 10-undecyn-1-ol, eight nC 30 alcohols containing-C≡ C-,(E)-C= C-or (Z)-C= C- group in the position 21 and/or 10 have been prepared. Spectral and gas-chromatographic properties (Kováts retention indices) of the novel compounds are described.
