Theoretical investigation of gold(I)-catalyzed intramolecular SEAr in isoxazole derivatives: Mechanisms, origin of regioselectivity, and role of hydrogen acceptor

A detailed theoretical study on the mechanism and regioselectivity of the Au(I)-catalyzed intramolecular electrophilic aromatic substitution (SEAr) in 4-substituted isoxazole derivatives is reported, using two model substrates, 4-(1-methylpropargyloxy)isoxazole (Series A) and 4-(1-methyl propargylamino)isoxazole (Series B). The obtained theoretical data reveal similar energy profiles in both series for the 6 endo dig heteroatom-assisted SEAr to form an alkenyl Au(I) intermediate. Then, in the series A, the 1,3-H-shift assisted by the 4-propargyloxyisoxazole leads to a final product and the catalyst regeneration. In contrast, in the series B, the elimination of proton by N-phenylbenzaldimine additive results in an iminium cation and dihydropyridine. In the next step, a hydride from dihydropyridine is accepted by the iminium cation to furnish pyridinium and N-benzylidenebenzenaminium species. Subsequently, protodeauration leads to a final product and N-phenylbenzylamine along with the catalyst regeneration. In the absence of N-phenylbenzaldimine additive, 4-(1-methylpropargylamino) isoxazole accepts the hydride instead of N-phenylbenzylamine and causes the consumption of the reactants, thus accounting for a low product yield. Furthermore, the regioselectivity and its origin as well as the rationalization of the deuterium labeling experiments are also examined and discussed in detail.

Unusual Retention of Isoxazole Ring under the Influence of 3-(Substituted nitrophenyl)-2-Isoxazoline during Catalytic Hydrogenation of Isoxazoline-Substituted Isoxazole Systems

The cleavage of the isoxazole ring during the Raney-Ni-promoted catalytic hydrogenation is prevented under the influence of 3-(substituted nitrophenyl)-2-isoxazoline in isoxazoline-substituted isoxazole systems, produced via 1,3-dipolar cycloaddition either on the Baylis-Hillman derivatives or Grignard products. Unexpectedly, the hydrogenations in these diastereomeric compounds were observed to exclusively yield products, wherein the methoxycarbonyl and the hydroxyl or the acetyl groups exist syn to each other.

Isoxazole mediated synthesis of 4-(1H)pyridones: improved preparation of antimalarial candidate GSK932121

A new synthesis of the antimalarial clinical candidate GSK932121 is described. This approach has two key reactions, the selective acylation of an unprotected 3-hydroxymethyl-5-methyl isoxazole and the reductive N-O bond cleavage of the previously functionalized isoxazole derivative, to give the 4-(1H)pyridone ring present in the final structure. The complete synthesis consists of 5 steps (versus 10 steps in previously published reports) and has enabled the preparation of the material in kilogram scale to support clinical studies.

Regiochemistry Discoveries in the Use of Isoxazole as a Handle for the Rapid Construction of an All-Carbon Macrocyclic Precursor in the Synthetic Studies of Celastrol

We have developed a convergent synthetic route to an all-carbon, 14-membered Z,E-macrocyclic bis-enone during our synthetic study of celastrol. The 1,3-dipolar cycloaddition of nitrile oxide and alkyne was employed for fragment coupling and introducing the 1,3-diketone moiety masked in the form of an isoxazole. We discovered that cycloaddition of the nitrile oxide and the enyne gave the rare 3,4-disubstituted isoxazole adduct under kinetic reaction conditions The,cycloaddition was found to be reversible, and the thermodynamic 3,5-disubstituted isoxazole could be obtained by isomerization of its 3,4-disubstituted isomer under elevated temperature. Our mechanistic studies support the role of hydrogen bonding in accelerating the isomerization. Consistent with our previous studies, the Z,E-macrocyclic bis-enone was found to be inactive toward the transannular bis-Michael reaction under the conditions evaluated.

DABCO-catalyzed sp(3) C-H activation: rapid access to isoxazole or coumarin-fused 3-quaternary carbon oxindoles and isoxazole-fused pyrrolidinones

A facile and efficient methodology was developed for the synthesis of isoxazole or coumarin-fused 3-quaternary carbon oxindoles and isoxazole-fused pyrrolidinones via DABCO-catalyzed sp(3) C-H activation of 5-methyl-isoxazole or 4-methylcoumarin. Furthermore, the biological activity of the isoxazole or coumarin-fused 3-quaternary carbon oxindoles 3 and 5 has been preliminarily demonstrated by in vitro evaluation against human prostate cancer cells PC-3 and human leukemia cells 1(562 by the MIT-based assays using the commercially available standard drug Cisplatin as a positive control. These results suggested that most of the compounds 3 and 5 showed considerable cytotoxicities to these two cell lines 1(562 and PC-3, and a methyl or an ethyl group of acrylates and an oxindole moiety located in the isoxazole-fused 3-quaternary carbon oxindoles 3 are beneficial for the activity. In addition, the activity of all the afforded isoxazole-fused pyrrolidinones 7 were also evaluated against Gram-positive bacteria Staphylococcus aureus (MTCC96) and Gram-negative bacteria Escherichia coli (ATCC25835) using Penicillin as a standard drug for Gram-positive organism or Streptomycin as standard drug for Gram-negative organism. The results demonstrated that most of the compounds 7 had comparable in vitro inhibitory activity against Gram-positive bacteria Staphylococcus aureus (MTCC96) with the positive control Penicillin. The results also indicated that isoxazole-fused pyrrolidinone analogs had significantly better inhibition ability against Gram-positive bacteria Staphylococcus aureus (MTCC96) than against Gram-negative bacteria Escherichia coli (ATCC25835).
