Enantioselective synthesis of (-)-jiadifenin, a potent neurotrophic modulator.

ABSTRACT: The first enantioselective synthesis of (-)-jiadifenin (1), a potent neurite outgrowth promoter isolated from the Illicium species, is described. The synthetic strategy builds upon bicyclic motif 6, which represents the AB ring of the natural product and proceeds in 19 steps and 1.1% overall yield. Key to our approach is a Mn(III)-mediated oxidation reaction of A ring that, following a regio- and diastereoselective ?-hydroxylation and methylation sequence, produces the desired functionalities of (-)-jiadifenin. The effect of synthetic 1 in NGF-mediated neurite outgrowth was also measured in PC-12 cells.

Enantioselective total synthesis of (-)-zampanolide, a potent microtubule-stabilizing agent.

Project description:An enantioselective total synthesis of zampanolide has been accomplished using a novel DDQ/Brønsted acid promoted cyclization as the key reaction. The synthesis features cross-metathesis to construct the trisubstituted olefin and a ring-closing metathesis to form the macrolactone. The final N-acyl aminal formation was stereoselectively accomplished by an organocatalytic reaction.

Enantioselective total synthesis of (+)-largazole, a potent inhibitor of histone deacetylase.

Project description:An enantioselective total synthesis of the cytotoxic natural product (+)-largazole (1) is described. It is a potent histone deacetylase inhibitor. Our synthesis is convergent and involves the assembly of thiazole 3-derived carboxylic acid with amino ester 4 followed by cycloamidation of the corresponding amino acid. The synthesis features an efficient cross-metathesis, an enzymatic kinetic resolution of a beta-hydroxy ester, a selective removal of a Boc-protecting group, a HATU/HOAt-promoted cycloamidation reaction, and synthetic manipulations to a sensitive thioester functional group.

Enantioselective Total Synthesis of (+)-Monocerin, a Dihydroisocoumarin Derivative with Potent Antimalarial Properties.

Project description:We describe here the enantioselective synthesis of (+)-monocerin and its acetate derivative. The present synthesis features an efficient optically active synthesis of the ?-hydroxy-?-lactone derivative with high enantiomeric purity using Sharpless dihydroxylation as the key step. The synthesis also highlights a tandem Lewis acid-catalyzed, oxocarbenium ion-mediated diastereoselective syn-allylation reaction, and a methoxymethyl group promoted methylenation reaction. We investigated this reaction with a variety of Lewis acids. A selective CrO3-mediated oxidation of isochroman provided the corresponding lactone derivative. The synthesis is quite efficient and may be useful for the preparation of derivatives.

Substituted Imidazoline Synthesis: A Diastereo- and Enantioselective aza-Henry Route to a Human Proteasome Modulator.

Project description:The first enantio- and diastereoselective synthesis of Tepe's human proteasome modulator is described. Routes to this and other highly substituted chiral imidazolines generally produce racemic material. Key to the route disclosed here is a gram-scale anti-selective aza-Henry reaction of an α-alkyl α-nitro ester nucleophile, catalyzed by a Bis(Amidine) [BAM] chiral proton complex, delivering the key intermediate in high yield as a single stereoisomer. The adduct is reduced to the amino ester and converted to an imidazoline.

Enantioselective Synthesis and Profiling of Potent, Nonlinear Analogues of Antimalarial Tetraoxanes E209 and N205.

Project description:Synthetic endoperoxide antimalarials, such as 1,2,4-trioxolanes and 1,2,4,5-tetraoxanes, are promising successors for current front-line antimalarials, semisynthetic artemisinin derivatives. However, limited solubility of second-generation analogues in biological-relevant media represents a barrier in clinical development. We present methodology for the synthesis of nonlinear analogues of second-generation tetraoxane antimalarials E209 and N205 to investigate reduced molecular symmetry on in vitro antimalarial activity and physicochemical properties. While maintaining good antimalarial activity and metabolic stability, head-to-head comparison of linear and nonlinear counterparts showed up to 10-fold improvement in FaSSIF solubility for three of the four analogues studied. Pharmacokinetic studies in rats comparing a selected nonlinear analogue 14a and its parent N205 showed improvement on oral absorption and exposure in vivo with more than double the AUC and a significant increase in oral bioavailability (76% versus 41%). These findings provide support for further in vivo efficacy studies in preclinical animal species.

Enantioselective Total Synthesis of (+)-EBC-23, a Potent Anticancer Agent from the Australian Rainforest.

Project description:We describe here an enantioselective synthesis of (+)-EBC-23, a potent anticancer agent from the Australian rainforest. Our convergent synthesis features a [3+2] dipolar cycloaddition of an olefin-bearing 1,3-syn diol unit and an oxime segment containing 1,2-syn diol functionality as the key step. The segments were synthesized in a highly enantioselective manner using Noyori asymmetric hydrogenation of a β-keto ester and Sharpless asymmetric dihydroxylation of an α,β-unsaturated ester. Cycloaddition provided isoxazoline derivative which upon hydrogenolysis furnished the β-hydroxy ketone expediently. A one-pot, acid-catalyzed reaction removed the isopropylidene group, promoted spirocyclization, constructed the complex spiroketal lactone core, and furnished EBC-23 and its C11 epimer. The C11 epimer was also converted to EBC-23 by chemoselective oxidation and reduction sequence. The present synthesis provides convenient access to this family of natural products in an efficient manner.

Enantioselective Synthesis of γ-Phenyl-γ-amino Vinyl Phosphonates and Sulfones and Their Application to the Synthesis of Novel Highly Potent Antimalarials.

Project description:Racemic and enantioselective syntheses of γ-phenyl-γ-amino vinyl phosphonates and sulfones have been achieved using Horner-Wadsworth-Emmons olefination of trityl protected α-phenyl-α-amino aldehydes with tetraethyl methylenediphosphonate and diethyl ((phenylsulfonyl)methyl)phosphonate, respectively, without any racemization. The present strategy has also been successfully applied to the synthesis of peptidyl vinyl phosphonate and peptidyl vinyl sulfone derivatives as potential cysteine protease inhibitors of Chagas disease, K11002, with 100% de. The developed synthetic protocol was further utilized to synthesize hybrid molecules consisting of artemisinin as an inhibitor of major cysteine protease falcipain-2 present in the food vacuole of the malarial parasite. The synthesized artemisinin-dipeptidyl vinyl sulfone hybrid compounds showed effective in vitro inhibition of falcipain-2 and potent parasiticidal efficacies against Plasmodium falciparum in nanomolar ranges. Overall, the developed synthetic protocol could be effectively utilized to design cysteine protease inhibitors not only as novel antimalarial compounds but also to be involved in other life-threatening diseases.

Enantioselective Synthesis of Azamerone.

Project description:A concise and selective synthesis of the dichlorinated meroterpenoid azamerone is described. The paucity of tactics for the synthesis of natural-product-relevant chiral organochlorides motivated the development of unique strategies for accessing these motifs in enantioenriched forms. The route features a novel enantioselective chloroetherification reaction, a Pd-catalyzed cross-coupling between a quinone diazide and a boronic hemiester, and a late-stage tetrazine [4+2]-cycloaddition/oxidation cascade.
