The ketone cis-undec-5-en-2-one (III) has been isolated as the main volatile component of the pedal glands of the bontebok Damaliscus dorcas dorcas [1]. Several syntheses of this compound are known: by the conjugateaddition of B-(hept-l-ynyl)-9-borobicyclo[3.3.1]nonane to methylvinylketone [2], by the alkylation of pent-4-yn-l-oi [3], and via dihydrojasmone [4]. All these syntheses are complicated
We have accomplished the asymmetric synthesis of (8S,9S,10R,6Z)-trihydroxyoctadec-6-enoic acid in optically pure form and determined the absolute configuration of the natural product on the basis of the stereodetermined chiral building block 7, which was prepared by the catalytic enantioselective allylic oxidation of 4,5-epoxycyclohex-1-ene using an S-configured N,N-bidentate ligand–copper catalyst
The invention relates to compounds of Formula (I). Compounds of the present invention are inhibitors of sphingosine kinase 3, and are useful in the treatment of various disorders and conditions, such as inflammatory disorders.
