7-trioxabicyclo[2.2.2]octane (5) was obtained from phosphorusoxychloride. Benzyl chloroformate was synthesized by the reaction of benzyl alcohol and triphosgene in good yield for the first time. N-r-Butyl-N-benzoylhydrazine(II) was prepared in a new and convenivent procedure with good yield. The reaction of 5 and II proceeded smoothly in the presence of sodium carbonate and afforded the desired compound

Benzyl chloroformate was synthesised by the reaction of benzyl alcohol and triphosgene in good yield for the first time. N-tert-Butyl-N-substituted benzoylhydrazines were prepared in a new and convenient procedure with good yields. A series of novel N'-tert-butyl-N'-substituted benzoyl-N-(substituted phenyl)aminocarbonylhydrazines and their derivatives were synthesised and evaluated for molting hormone mimicking activity. The results of bioassays showed that the title compounds exhibit good larvicidal activities and toxicity assays indicated that the title compounds can induce a premature, abnormal and lethal larval molt. We have found that the title compounds possess potential anticancer activities. (C) 2001 Elsevier Science Ltd. All rights reserved.

N-tert-butyl-N-substituted benzoylhydrazines were prepared in two convenient procedures with good yields, subsequent reaction with substituted phenylisocyanates in 1,2-dichloroethane provided a series of novel N'-tert-butyl-N'-substituted benzoyl-N-(substituted phenyl)aminocarbonylhydrazines. Further treatment with oxalyl chloride gave their derivatives in good yields. The title compounds exhibit moderate larvicidal activities and anticancer activities.
