  摘要：

  The effect of substitution at the 'central methane' on the photoreactivity of 3-benzylfuran-2(5H)ones 5a-g was investigated. Despite its di-pi-methane structure, photochemical arylation was effected to give substituted indenofuranones 6 in good yields. Only the substitution by phenyl caused the di-pi-methane rearrangement to give a cyclopropanofuranone 18g in moderate yield.

  The effect of the ‘central methane’ substitution on the di-π-methane rearrangement in 4-benzyl-2,5-dihydrofuran-2-ones 8a–d was investigated. Significant enhancement of efficiency in the rearrangement leading in high combined yields to two isomeric products, endo-12 and exo-12, is discussed in terms of both the substituent effects at the benzylic carbon and the restrained features of the ring-enrolled

  研究了“中央甲烷”取代对4-苄基-2,5-二氢呋喃-2-酮8a - d中二-π-甲烷重排的影响。讨论了重排效率的显着提高，导致高收率合成了两个异构体，endo - 12和exo - 12，分别针对苄基碳上的取代基效应和环式π系统的受限制特征进行了讨论。 。化学选择性差异的起因与3-芳基化合物5的光芳基化产物6相比 还研究了光辐照产生的结果，并通过假定烯酮系统的β位置具有更高的反应性进行了合理化。

  Bridged-tricyclic cyanoguanidines 1 were found to be active as insecticides. The preparation and structure-activity relationships of oxacyclic (X=O) and carbocyclic (X=CH2) analogues of 1 is described. Compounds 1 were found to inhibit acetylcholinesterase with IC50 values comparable to the organophosphate Paraoxon. Unlike organophosphates. cyanoguanidines 1 were shown to reversibly bind acetylcholinesterase. This mode of action is shared by the structurally-related natural product Huperzine A.
