Synthesis of novel isoxazole ring containing quinazoline derivatives and in vitro inhibitory activity against PTP alpha and PTP epsilon

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. Their structures were confirmed by IR, HNMR and ESI-MS spectra. The compounds 6a, 6c and 6d were assayed in vitro activity against PTP alpha, PTP epsilon, and showed that the tested compounds had no notable inhibitory activity in the concentration of 20 mu g/mL.

Rapid and High-Yield Electrosynthesis of Benzisoxazole and Some Derivatives

Cyclic voltammetry and controlled-potential (bulk) electrolysis have been used to explore the electrochemical reduction of o-nitrobenzaldehyde (o-NBA) and 8 other aldehydes and ketones at glassy carbon cathodes in dimethylformamide containing various tetraalkylammonium tetrafluoroborate salts along with a proton donor (4-chlorophenol). Cyclic voltammograms for reduction of o-NBA exhibit three cathodic peaks attributable in succession to (a) one-electron generation of the nitro radical-anion, (b) three-electron formation of the hydroxylamine, and (c) two-electron production of benzisoxazole (anthranil). These findings have been employed to develop efficient controlled-potential (bulk) electrosyntheses of the following compounds: benzisoxazole, methylbenzo[c]isoxazole, [1,3]dioxolo[4 ‘,5 ‘,4,5]benzo[1,2-c]isoxazole, naphtho[2,3-c]isoxazole, 6-chlorobenzo[c]isoxazole, 6-methoxybenzo[c]isoxazole, 3-methyl-benzo[c]isoxazole, 3-isopropylbenzo[c]isoxazole, and 3-phenylbenzo[c]isoxazole. In addition, we have examined the use of a variety of proton donors to optimize the production of the desired product, and we have been able to recover the proton donor at the conclusion of the electrosynthesis. In each case, the synthesized product was separated by means of normal phase chromatography and identified with the aid of NMR spectros-copy, gas chromatography (GC), and gas chromatography-mass spectrometry (GC-MS). Isolated yields of the desired products range from 63 to 92 %. Moreover, our electrosyntheses are catalyst-free, environmentally green, and rapid (similar to 30 min).
