title: Synthesis and antioxidant activity of a new class of bis and tris heterocycles.
abstract: A series of novel heterocycles, bisbenzoxazolyl/benzothiazolyl/benzimidazolyl pyrazoles/isoxazoles/pyrimidines were synthesized and evaluated for their antioxidant activity. The bisbenzoxazolylisoxazole 10 exhibited good antioxidant activity when compared with the standard ascorbic acid.
