5-Chloro-3-methyl-4-nitroisothiazole (III) was prepared by nitration of 5-chloro-3-methyliso-thiazole. Compound III was found to exhibit significant antifungal activity in vitro against a wide spectrum of fungi. The synthesis of 3-methyl-4-nitro-5-nitroamino, 5-carboxamido, 5-N,N-dimethylamino and 5-β-hydroxyethylaminoisothiazole are here reported. The synthesis of 3-methyl-4-nitroso-5-ethylthioisothiazole
