The reaction of dimethyl malonate (I) with 3-(tert-butyldimethylsilyloxy)propyl iodide (II) by means of NaH in THF gives the alkylmalonate (III), which by a new alkylation with allyl bromide (IV) and NaH in DME affords the dialkylmalonate (V). The reduction of (V) with LiBH4 in THF yields the 1,3-propanediol (VI), which is cyclized with 2,2-dimethoxypropane and CSA in dichloromethane giving the 1,3-dioxane (VII). The ozonolysis of the double bond of (VII) with O3 in dichloromethane yields the aldehyde (VIII), which is protected by heating with cyclohexylamine (IX) to afford the imine (X).The condensation of (X) with 8(E)-decenal (XI) by means of LDA in ethyl ether gives the unsaturated aldehyde (XII), which is treated with Pmb-Cl and KH in DME/HMPA to yield the enol ether (XIII). The desilylation of (XIII) with TBAF in THF gives the propanol derivative (XIV), which is oxidized with SO3/pyridine to the corresponding aldehyde (XV). The condensation of (XV) with 4-(triisopropylsilyloxy)-1(E)-butenyl iodide (XVI) by means of BuLi in THF, followed by oxidation of the intermediate alcohol with SO3/pyridine provides the unsaturated ketone (XVII).
