Abstract

1,203,040. Nitrofuryl-isoxazoles. J. R. GEIGY A.G. 14 Feb., 1968 [15 Feb., 1967], No. 7289/67. Heading C2C. [Also in Division A5] Nitrofuryl-isoxazoles of Formula I, and their tautomers of Formulµ Ia and Ib, in which each of R 1 and R 2 is aC 1-4 alkyl group which is unsubstituted or hydroxy-, alkoxy- or halogensubstituted, C 3-4 alkenyl, C 5-6 cycloalkyi or C 1-4 alkoxy-carbonyl, or in which R 1 is C 3-4 alkenyl and R 2 is hydrogen, are prepared by reacting a reactive functional derivative of a carboxylic acid of Formula II with a compound of Formula III or with a derivative capable of producing a compound of Formula III under the reaction conditions. The compounds in which R 2 is not hydrogen are novel. 3 - (5 - Nitro - 2 - -furyl) - 4 - chlorocarbonyl - 5- amino-isoxazole is prepared by hydrolysing 3- (5 - nitro - 2 - furyl) - 4 - tert. - butoxycarbonyl- 5-amino-isoxazole and reacting the resulting 3 (5 - nitro - 2 - furyl) - 4 - carboxy - 5 - aminoisoxazole with thienyl chloride.
