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.

The readily available 3-methylisoxazol-5-amine (1) has been used as a key intermediate for the synthesis of isoxazolo[5,4-b]pyridine, pyrrolo[3,2-d]isoxazole, isoxazolo[5,4-b]azepine-4,7-dione and isoxazole derivatives via its reactions with some chemical reagents. Sixteen compounds were designed to study their cytotoxic properties against three human cell lines: colorectal carcinoma (HCT-116), prostate cancer (PC3) and normal lung fibroblast (WI-38), using the MTT colorimetric assay. 5-Fluorouracil, a well-known anticancer drug, was used for comparison. Among the tested candidates, pyrrolo[3,2-d]isoxazole 5 and isoxazole derivatives 11-14 showed the highest activity against the tested cancer cell lines with good selectivity by their lower toxicity against normal cells.

Synthesis of Isoxazole- and Oxazole-4-carboxylic Acids Derivatives by Controlled Isoxazole-Azirine-Isoxazole/Oxazole Isomerization

The first synthesis of isoxazole-4-carboxylic acid derivatives by domino isoxazole-isoxazole isomerization is reported. Fe(II)-catalyzed isomerization of 4-acyl-5-methoxy-/5-aminoisoxazoles (dioxane, 105 degrees C) leads to the formation of isoxazole-4-carboxylic esters and amides in good yields. 4-Formyl-5-methoxyisoxazoles give methyl oxazole-4-carboxylates under the same reaction conditions. Fe(II)-catalyzed isomerization of 4-acyl-5-methoxyisoxazoles under milder conditions (MeCN, 50 degrees C) allows the preparation of transient 2-acyl-2-(methoxycarbonyl)-2H-azirines. The azirines isomerize quantitatively either into isoxazoles under catalytic conditions (dioxane, 105 degrees C) or into oxazoles under noncatalytic thermolysis (o-dichlorobenzene, 170 degrees C). The mechanism of the isomerization and dependence of the reaction routes on substituents at starting isoxazole core and reaction conditions are discussed on the basis of DFT calculations.

Semisynthesis and acaricidal activities of isoxazole and pyrazole derivatives of a natural product bisdemethoxycurcumin

Sixteen isoxazole and pyrazole derivatives of bisdemethoxycurcumin (BDMC) modified in beta-diketone were synthesized, and their structures were confirmed by IR, H-1 NMR, C-13 NMR, MS and elemental analysis. Preliminary acaricidal activities against female adults of Tetranychus cinnabarinus (Boisduval) and Panonychus citri (McGregor) were evaluated using the slide-dip method. The results indicated that some of these compounds exhibit more pronounced acaricidal activity than BDMC, especially compound 4, which displays acaricidal activity comparable to that of pyridaben.
