The o-dihydroxy- (2a-b), dimethoxy (3a-b), ethylendioxy- (4a-b) and macrocyclic polyethers (4c-i) are the initial compounds while the 2,4-dinitrophenylhydrazone compounds (5a-d, 6a-i) represent new derivatives. Novel hydrazone compounds were synthesized from the corresponding cyclic ketones (4a-i) and 2,4-dinitrophenylhydrazine in H2SO4/EtOH/H2O solution at room temperature for 1 h. The structures
