Full textWith the aim of preparing tocopherol (Vitamin E) from bulk chemicals as citral, linalool and dihydromyrcen, the condensation of trimethyhydroquinone with these terpenic derivatives has been reexamined. Suitable conditions have found and both the chroman and the chromen that formed, respectively, have been converted in the target molecule by means of epoxidation – Al(Oi-Pr)3 promoted isomerization – Wurtz like coupling sequence. Besides, an efficient bis-functionnalization of dihydromyrcen has been realized by performing sequentially an epoxidation and a chlorosulfanylation. The vinylic sulfides obtained has been converted into either dehydroisophytol and a dehydrophytylsulfone respectively by a piperidine induced Mislow-Evans rearrangement of corresponding sulfoxides and DBU isomerisation of a vinylic sulfone. Next, efficient conditions have been discovered to selectively rearrange a sulfonated cyclobutanediol, itself derived from the Yang cyclisation product of 2,3-pentanedione into a cyclopropyl ketosulfone. This paves the was for a short synthesis of tocopherol from 2-pentene and geranylacetone. Finally, enantiomerically hydroxysulfone has been prepared by mean of a very simple desymetrization process of a prochiral diol with an enzyme. Repeated condensation of this sulfone with the (R)-epoxide of 2-butene-1,4-diol has been successfully accomplished, with the result of a very short, highly stereoselective synthesis of the Morken polypropionate intermediate to borrelidine ; this has to be considered as a formal synthesis of this antibiotic macrolide

Full textMy PhD thesis mainly involves the enantioselective synthesis of the Milnacipran's analog, a trisubstituted cyclobutane bearing two contiguous stereogenic centers. We have devised a conventional approach which consists of an intramolecular SN2 cyclization. After an acidic treatment, the key intermediate lactone was isolated with an ee > 99%, which was converted to the Milnacarre with no erosion of the ee value. We have also interested in the nanometric formulation of Podophyllotoxine derivatives. The natural product was designed to bear a hydrophilic and hydrophobic side chain. Its micellar solution was evaluated in vitro, in vivo and the obtained resuls were shown to be promising.We have also studied two methodologies: the reactivity of glycidyl ether toward alkyllithium reagents and oxydation of hydroxylamines to nitrone using triphenylbismuth carbonate. We observed in the former case an original rearrangement of the substrate to a vicinal diol, while in the latter case we have developped a mild condition to perform an tandem oxydation/1,3-dipolar cycloaddition in situ with a strained alkyne

Full textThe overall aim of this Ph. D work is the total synthesis of macrolactin A. Macrolactin A is a 24-membered polyene macrolide exhibiting antiviral activity against type I and II Herpes simplex and against HIV. Until now only a few total and partial synthesis were reported. A new and convergent synthesis of C12-C24 fragment has been achieved during the Ph. D research period. This synthesis has been accomplished using consecutive organometallic additions to aldehydes and the novel application of eliminative reduction to introduce the E,E-diene moiety. The synthesis features the application of chiral sulfoxides and the novel use of a versatile 1,3-diol synthon. The two stereogenic centers of the anti-1,3-diol synthon were introduced utilizing a chiral starting epoxide and the diastereoselective reduction of a β-hydroxyketone. One of the key step of the synthesis of this synthon is the functional transformation of a protected homoallylic alcohol into a α-hydroxyketone with KMnO4. The chiral center of C23 was introduced by the diastereoselective reduction of a β-ketosulfoxide. The reductive elimination with sodium amalgama offered an efficient and highly stereoselective mean to introduce directly in one step the C16-C19 (E,E) diene. Our approach furnished the C12-C24 fragment of macrolactin A in 14 steps and 6% overall yield. Studies on the upper part of the molecule are still in course
