摘要:ABSTRACT(#br)We describe an efficient and very easy two-step preparation of a new C6 acetylenic homologating agent 4(#br). This compound is a precursor of 1,4-enyne and 1,3-eneallene units which are useful building blocks for the total synthesis of modified PUFAs.

摘要:Abstract(#br)An easy preparation of symmetric Cis-skipped polyenic hydrocarbons 1 to 5 combining the controlled classical Wittig reaction or the oxidative dimerization of phosphoranes is described.

摘要:Abstract(#br)Chiral building blocks derived from l -diethyl tartrate are derivatized into various chiral arachidonic acid analogs based on a dioxane core.

摘要:Abstract(#br)The first total synthesis of 4( RS )-F 4t -isoprostane methyl ester 1 is described using diacetone- d -glucose as starting material. This new isoprostane (neuroprostane) would be very useful in neurological studies as a potent lipid peroxidation index to obtain an in...

摘要:Abstract(#br)a new preparation of the bifunctionalized unsaturated C6 homologating agent 2b which is an efficient synthetic tool is described. This method is atom economic, very efficient on grams scale and easy to handle from cheap commercially available 1,4-cyclohexadiene. Synt...

摘要:Abstract(#br)The convergent synthesis in high enantiomeric and diastereoisomeric purity of (11 R ,17 S )-11,17-dimethylhentriacontane, a communication pheromone of ant Camponotus vagus is described. The stereogenic centres were introduced from commercially available ( R )-citrone...

摘要:Abstract(#br)Controlled Wittig condensations onto chiral building blocks derived from L-diethyl tartrate led to various chiral arachidonic acid analogs based on a dioxolan core.

摘要:Abstract(#br)Ring rearrangement metathesis (RRM) strategies are proposed for the expeditious synthesis of the cores of naturally occurring cyclic polyethers of the dysiherbaine and acetogenin families, as well as a hybrid compound, from 8‐oxabicyclo[3.2.1]octenes.

摘要:Abstract(#br)The 13C NMR of ethylenic carbon atoms in the methylene‐interrupted cis double bonds as found in polyunsaturated fatty acids (PUFAs), their precursors and analogs was studied. The chemical shifts of unsaturated carbon atoms are strongly dependent on a ...
