The synthesis of four analogs of philanthotoxin is described. The preliminary bioassay showed that these compounds all had good insecticidal activities, and the compound 6a had the best killing effect.

A lanthanum adduct with BQEB was spothesized and its structure was characterized by X-ray crystal analysis. The La(III) is ten-coordinated to the three No3- and four H2O. Two podand molecules are linked to the coordination core by four hydrogen bonds. The crystal is packed in the manner of .LLMLLMLL.展开更多
