A short total synthesis of the published structure of racemic trichodermatide A is reported. Our synthesis involves a Knoevenagel condensation/Michael addition sequence, followed by the formation of tricyclic hexahydroxanthene-dione and a diastereoselective bis-hydroxylation. The final product, the structure of which was confirmed by X-ray crystallography, has NMR spectra that are very similar, but not identical, to those of the isolated natural product. Quantum chemically computed 13C shifts agree well with the present NMR measurements. (Chemical Equation Presented).
A CONVENIENT METHOD FOR THE STEREOSPECIFIC SYNTHESIS OF (E)-3-ALKEN-1-OLS UTILIZING THE RING-OPENING REACTION OF 2,3-DIHYDROFURAN WITH ORGANOCUPRATES

(E)-3-Alken-1-ols were stereospecifically synthesized in good yields utilizing the regioselective nucleophilic ring-opening reaction of 2,3-dihydrofuran with several kinds of organocuprates under mild conditions.
Metal/Ammonia Reduction of Ethers of 3-Decyn-1-ol: Effects of Structure and Conditions on Cleavage and Rearrangement
Doolittle, Robert E.,Patrick, Delrea G.,Heath, Robert H.
, p. 5063 - 5066 (1993)
Reduction of the THP, ethyl, tert-butyl and tert-butyldimethylsilyl (TBDMS) ethers of 3-decyn-1-ol with sodium in ammonia/THF results in extensive hydrogenolysis of the carbon-oxygen bond and concomitant bond migration, producing a mixture of 2- and 3-decenes and a very low yield of the desired (E)-homoallylic ether.Reduction in the presence of 2-methyl-2-propanol led to excellent yields of the desired (E)-3-decenol ethers.The 4- and 5-decyn-1-ol ethers were reduced normally to the (E)-decen-1-ol ethers except in the case of the TBDMS ethers which were cleaved to the (E)-alcohols under some of the reaction conditions.
INTRAMOLECULAR HYDROSILATION OF ACETYLENES: REGIOSELECTIVE FUNCTIONALIZATION OF HOMOPROPARGYL ALCOHOLS
Tamao, Kohei,Maeda, Kimio,Tanaka, Tetsu,Ito, Yoshihiko
, p. 6955 - 6956 (1988)
Platinum-catalyzed intramolecular hydrosilation of hydrodimethylsilyl ethers of homopropargyl alcohols proceeds regioselectively in a 5-exo-dig mode.The resulting vinylsilanes can be transformed into 3-alkanon-1-ol and 3-bromo-3-alken-1-ol derivatives by H2O2 oxidation and bromine cleavage, respectively.

The trans-selective variant of the Wittig reaction can be successfully applied to the synthesis of alkenol-type pheromones.

Tandem IBX-Promoted Primary Alcohol Oxidation/Opening of Intermediate β,γ-Diolcarbonate Aldehydes to (E)-γ-Hydroxy-α,β-enals
Kumari, Anupama,Gholap, Sachin P.,Fernandes, Rodney A.
, p. 2278 - 2290 (2019/06/17)
A tandem IBX-promoted oxidation of primary alcohol to aldehyde and opening of intermediate β,γ-diolcarbonate aldehyde to (E)-γ-hydroxy-α,β-enal has been developed. Remarkably, the carbonate opening delivered exclusively (E)-olefin and no over-oxidation of γ-hydroxy was observed. The method developed has been extended to complete the stereoselective total synthesis of both (S)- and (R)-coriolides and d-xylo- and d-arabino-C-20 guggultetrols.
Influence of the chemical structure on odor qualities and odor thresholds in homologous series of alka-1,5-dien-3-ones, alk-1-en-3-ones, alka-1,5-dien-3-ols, and alk-1-en-3-ols
Lorber, Katja,Schieberle, Peter,Buettner, Andrea
, p. 1025 - 1031 (2014/03/21)
Odor qualities and odor thresholds in air in homologous series of synthesized alk-1-en-3-ols and alka-1,5-dien-3-ols and their corresponding ketones were evaluated by gas chromatography-olfactometry. In the series of the alk-1-en-3-ols and alk-1-en-3-ones the odor quality changed successively from pungent for the compounds with five carbon atoms via metallic, vegetable-like for the six- and seven-carbon odorants to mushroom-like for the compounds with eight and nine carbon atoms. With further increase in chain length the mushroom-like impression decreased and changed to citrus-like, soapy, or herb-like. In both series, two odor threshold minima were found for the six-carbon and also for the eight- and nine-carbon odorants, respectively. In contrast to this, the odor qualities in the series of the (Z)- and (E)-alka-1,5-dien-3-ols and their corresponding ketones did not change significantly with geranium-like, metallic odors and an increasing mushroom-like odor note with increasing chain length. The lowest thresholds were found for the eight- and nine-carbon (Z)-compounds, respectively.

The enantiomer [(+)-1] of the nonenolide natural product microcarpalide [(-)-1] has been prepared from (S)-malic acid (3) and 3-decyn-1-ol (11) via a sixteen step sequence involving, inter alia, two metathesis processes.
