Two novel series of quinonederivatives have been synthesized. Thus, condensation of 2‐ethoxycarbonylmethylthio‐; 3‐ethoxycarbonylmethylthio‐2‐methyl‐ and 3‐ethoxycarbonylmethoxy‐2‐methyl derivatives of 1,4‐naphthoquinone with substituted phenylhydrazines afforded the corresponding hydrazones, while cyclization of the same quinones with the same substituted hydrazines in glacial acetic acid gave the
