  Synthesis and Herbicidal Activity of 1H-1,4-Benzodiazepine-2,5-diones

  摘要：

  A series of 1H-1,4-benzodiazepine-2,5-diones, which have been found to inhibit photosystem II electron transport, were evaluated for their herbicidal activity. Many of the analogues tested exhibited moderate to good herbicidal activity both preemergence and postemergence. The structure-activity relationships were probed by substitution in both the benzene and diazepine ring. Among the variations investigated, it was found that maximal herbicidal activity was obtained by substitution at C-7 and C-9 in the aromatic portion and by bulky aliphatic substitution at N-4 while leaving N-1, C-6, and C-8 unsubstituted.

  Palladium(II)-mediated coupling reactions of bromo- and iodo-1H-1,4-benzodiazepine-2,5-diones. A route to functionalized benzodiazepinediones

  摘要：

  A series of 7-, 8-, and 9-bromo- and iodo-1,4-benzodiazepine-2,5-diones have been prepared and examined as substrates for palladium(II)-mediated coupling reactions with alkenes, alkynes, arylstannanes, and heteroarylstannanes. The benzodiazepinediones 6a,e,g were prepared from the reaction of o-nitrobenzoyl chlorides 3a-c and methyl tert-butylglycinate followed by nitro reduction and cyclization. Regioselective halogenation gave 6c,d,f. Bromo- and iodobenzodiazepinediones 6c,d,f,g were then converted to alkenyl-, alkynyl-, aryl-, and heteroaryl-substituted benzodiazepinediones in moderate to good yield in the presence of palladium(II).
