Abstract
Process for the preparation of new 5-nitro-2-furyl-iaoxazole derivatives of the general formula I ** (See formula) ** in which R means a group -CN, -CO-OR1 or ** (See formula) ** R1 means an alkyl group with 1 to 6 carbon atoms, straight or branched chain, unsubstituted or substituted by the hydroxyl, alkoxy or halogen group; an alkenyl group with 3 or 4 carbon atom, straight or branched chain; or a cycloalkyl group, R2 means hydrogen R3 means hydrogen; an alkyl group with 1 to 12 carbon atoms, straight or branched chain, unsubstituted or substituted by the hydroxyl, alkoxy or halogen group; an alkenyl group with 3 or 4 carbon atoms, straight or branched chain; a cycloalkyl group; a carboalkoxylic group whose alkyl radical consists of an alkyl group with 1 to 5 carbon atoms, straight or branched chain, a carbomoyl group, O well R2 and R3 together are an alkylene chain having 2 to 7 carbon atoms, straight or branched and uninterrupted or interrupted by an oxygen atom, nitrogen or sulfur, characterized by reacted a compound 5-nitro-2-furohidroxamoilhalogenado of the formula II ** (See formula) ** in which X means a halogen atom, with a reactive methylnane compound, of the general formula III ** (See formula) ** in which And it means hydrogen or an alkali metal and R means the same as that stated above.
