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.

7-Nitro-4-chrolo-quinazoline (4) was synthesized by two-step reactions using 4-nitro-2-aminobenezic acid and formamidine acetate as starting materials. And then, 3-(substituted-phenyl)isoxazole-5-methylamine derivatives 5a similar to 5e were synthesized by synthesizing substituted benaldehyde oxime, [3+2] dipolar cycloaddition reaction with propargyl alcohol, then acylation with methanesulfonyl chloride, substitution with NaN(3) and reduction with Zn/NH(4)Cl. Subsequently, 3-(substituted-phenyl)isoxazole-5-methylamino-4(3H)-quinazoline derivatives 6a similar to 6e were obtained by solid-grinding 5a similar to 5e and 4 under the basic Al(2)O(3) at room temperature.

Simple primary amine catalyzed aerobic reductive ring-cleavage of isoxazole motif

A clean and highly efficient catalytic aerobic reductive ring-cleavage of 3-methylanthra[1,2-c]isoxazole-6,11-dione to 1-amino-2-acetylanthraquinone was performed using simple organic amines as organocatalysts and water as a green reaction medium. This method provides a new clean transformation of isoxazole-containing compounds to the corresponding ortho-amino ketones. The catalytic performance of various organic amines was carefully screened, and simple organic primary amines were found to be promising practical catalysts with outstanding catalytic performance. Isopropylamine as the organocatalyst gave 97.2% conversion of 3-methylanthra[1,2-c]isoxazole-6,11-dione, with 97.2% selectivity to 1-amino-2-acetylanthraquinone, in the presence of oxygen only, using 1 equiv. of hydrazine hydrate at room temperature for 3 h. A possible mechanism is also proposed. (C) 2015, Dalian Institute of Chemical Physics, Chinese Academy of Sciences. Published by Elsevier B.V. All rights reserved.
