Аннотация:
The reaction of 3-nitro-2-trichloromethyl-2H-chromenes with hydrazine hydrate in ethanol at room temperature results in 3,4-trans, 4,5-trans-3-(2-hydroxyaryl)-4-nitro-5-trichloromethylpyrazolidines in 56–73% yields; the structures of these compounds were established by 1H NMR, 2D COSY and 2D NOESY spectra.
