The first Z-stereoselective method was developed for the synthesis of unsaturated acids containing a 1Z,5Z,9Z-triene moiety in 61–64% yields using the new Ti-catalyzed cross-coupling of oxygen-containing and aliphatic 1,2-dienes as the key synthetic step. It was shown for the first time that trienoic acids with non-methylene-interrupted Z-double bonds show moderate cytotoxic activities against tumor cell lines (Jurkat, K562, U937, HL60, HeLa), human embryonic kidney cells (Hek293), normal fibroblasts and human topoisomerase I (hTop1) inhibitory activity in vitro. The synthesized acids efficiently initiate apoptosis of Jurkat tumor cells, with the cell death mechanism being activated by the mitochondrial pathway. A probable mechanism of topoisomerase I inhibition was also hypothesized on the basis of in silico studies resorting to docking. The activation and inhibition of the most versatile intracellular signaling pathways (CREB, JNK, NFkB, p38, ERK1/2, Akt, p70S6K, STAT3 and STAT5 tyrosine kinases) responsible for cell proliferation and for initiation of apoptosis were studied by multiplex assay technology (Luminex xMAP).

The invention discloses a method for synthesizing cis-3-tetradecanoacetate and trans-3-tetradecanoacetate. The method comprises the following steps: (1) preparing 3-tetradecyne alcohol-1; (2) preparing cis-3-tetradecenol-1; (3) preparing trans-3-tetradecenol-1; and (4) preparing the cis-3-tetradecanoacetate and trans-3-tetradecanoacetate. The method is used for synthesizing cis-3-tetradecanoacetate and trans-3-tetradecanoacetate which are main components of gyplure of holcocerus insularis Staudinger; the raw materials for reaction are easily obtained; the cost is low; technical processes are short; reaction conditions are mild; the operation is simple, convenient and free from risk; the product is easily separated; the yield is high; and massive production can be carried out.

3-Alkyn-1-ols as intermediate synthons in the preparation of some Lepidoteran sex pheromones were utilized.Characteristic fragmentations reflecting the position of the triple bond were found in the mass spectra of 3-alkyn-1-ols and alkyn-1-yl acetates in contrast to 1-tert-butoxy-alkynes.A partial isomerization of 1-tosyloxy-3-(Z)-octene to 1-bromo-3-(E)-octene within the reaction with NaBr in DMF was noticed by GC and 13C-n.m.r., for which a mechanism involving homoconjugation in an intermediate non-classical carbonium ion was suggested.
