PROCESS OF PRODUCTION OF DEHYDROLINALYL ACETATE (II)

The present invention is related to a novel and improved process for the production of dehydrolinalyl acetate (DLA), which lUPAC name is acetic acid 1 -ethynyl-1,5- dimethyl-hex-4-enyl ester, starting from dehydrolinalool (DLL), which lUPAC name is 3,7-dimethyloct-6-en-1 -yn-3-ol, by acetylation.

Construction of 1,5-enynes by stereospecific Pd-catalyzed allyl-propargyl cross-couplings

The palladium-catalyzed cross-coupling of chiral propargyl acetates and allyl boronates delivers chiral 1,5-enynes with excellent levels of chirality transfer and can be applied across a broad range of substrates.
