Description

General description

3-Amino-5-methylisoxazole is the major intermediate formed during sulfamethoxazole biodegradation by Pseudomonas psychrophila strain HA-4[1]. It is the intermediate formed during the photocatalytic degradation of sulfamethoxazole (SMX)[2].

Application

3-Amino-5-methylisoxazole was used in synthesis of:

• naphtho[1,2-e][1,3]oxazines[3]
• series of 1-aryl-4-methyl-3,6-bis-(5-methylisoxazol-3-yl)-2-thioxo-2,3,6,10b-tetrahydro-1H-pyrimido[5,4-c]quinolin-5-ones, having potential mosquito larvicidal activity[4]
• hydroxylamines of sulfadiazine and sulfamethoxazole[5]
