Abstract: Benzothiazole, benzoxazole, and benzimidazole derivatives substituted with a γ-lactone, coumarin or pyrazolone cycle have been synthesized. Condensation reactions of these derivatives with aromatic aldehydes were studied. The structure of the products was proved by IR and 1H NMR spectra. The synthesized compounds are expected to have plant growth stimulating activity.
