Full textA non-chiral pool approach to the 8b-azaacenaphthylene ring system of the frog poison alkaloid (-)-205B has been developed. This rare tricyclic alkaloid has been of considerable synthetic interest in recent years owing to its potential biological activity against neuronal disorders. However, due to lack of material, a detailed study of the mode of action of this natural product has not yet been reported. Our strategy features several noteworthy transformations. A highly diastereoselective thermal [2+2] cycloaddition and a ring expansion through Beckmann rearrangement generates the functionalised lactam intermediate. An efficient vinylogous Mannich reaction then provides access to a butenolide, which subsequently leads to an indolizidinone ring system. After installation of a methyl group on this bicyclic intermediate, a relatively unexplored aza-Prins cyclization has been successfully employed to obtain an advanced intermediate, possessing the desired tricyclic system found in the natural product. This approach has laid a solid foundation for a novel access to this potentially important but scarce alkaloid extracted from a neotropical frog Dendrobatus pumilio that is threatened to be endangered

Full textAn effective procedure for conversion of glucal to α,β-unsaturated chiral γ-pyrone synthon which should be suitable for preparing natural products is reported in this work. Additionally an application to a total synthesis of a chiral mycotoxin trichothecene model was elaborated. Our plan for the construction of a chiral intermediate to mycotoxin trichothecene begins by the regioselective protection of the primary alcohol group as a silyl ether. Subsequent selective oxidation or protection of the allylic alcohol of glucal has been developed. At this point, the C-4 hydroxyl was acetylated and reduced photochemically to the corresponding disilyl or monosilylether 4-deoxyglucal : Regioselective oxidation of 3-t-butyldimethylether with PCC gives α,β -unsaturated 2,3,4-trideoxy-δ-lactone. Oxidation with buffered pyridinium chlorochromate (PCC)of 3-triethylsilylether give a mixture of δ -lactone and γ-pyrone α,β -unsaturated in ratio 1 : 2. Carefull deprotection of the triethylsilyl group at C-3 with buffered silica gel affords the corresponding 4-deoxyglucal. Final oxidation of this 4-deoxyglucal by FETIZON-GOLFIER reagent (Ag2co3/celite) leads to α,β -unsaturated γ-pyrone in high yield (90 %). A more attractive and shorter route involves use of the same silylated protecting group in the side chain followed by selective C-3 OH oxidation, C-4 OH acetylation, C-3 ketone reduction (LTBA or (NaBH4 + Ce3+) and C-4 photochemical deoxygenation giving the required intermediate 4-deoxyglucal. Stereoselective [2 + 2] photocycloaddition of acetylene to α,β -unsaturated γ-pyrone derived from D-glucal was obtained as an intermediate to the synthesis of a chiral trichothecene model

Full textL-Tartaric acid (TA) is an abundant natural by-product of the wine industry. It is a polyfunctional, chiral and low cost starting material particularly interesting for the preparation of optically pure products. On the other hand, trifluoromethyl compounds have important applications in various fields, in particular as bio-active products where chirality is often a central problem. This project was aimed towards the synthesis of enantiopure trifluoromethylated synthons based on TA scaffold. The synthesis is based on the chemo- and diastereoselective nucleophilic trifluoromethylation of TA derived keto-amides, followed in-situ by an alkylation affording the corresponding alkoxy-trifluoromethylcarbinol. The next key step is a one-pot deprotection-oxidation process leading to -trifluoromethyl--alkoxy-aldehydes. The residual amide moiety in the intermediate trifluoromethylcarbinols was converted into a ketone, which underwent various diastereoselective nucleophilic additions (hydrides, magnesium reagents, CF3TMS). Some adducts were further converted into two different enantiopure compounds from one initial TA scaffold. The functionalized enantiopure aldehydes were applied, via intermediate amino-ethers or amino-alcohols, to the preparation of a variety of original and enantiopure aza-heterocycles, bearing a pseudo-quaternary trifluoromethylated chiral carbon: morpholines, oxazepanes, aziridines. The overall process is an interesting way to convert TA into a wide range of high-value added enantiopure trifluoromethyl containing building blocks, especially in heterocyclic series
