Synthesis of the allelochemicals heliannuols A and K, and the sesquiterpene helianane is described. A regioselective cleavage of a benzo-fused oxabicyclo(5.1.0)octane system under hydrogenation as well as radical induced condition was developed to generate the basic benzoxocane ring system of these unusual sesquiterpenes.
描述了化感物质Heliannuols A和K,以及倍半萜烯Helianane的合成。苯并稠合的氧杂双环(5.1.0)辛烷体系在氢化以及自由基诱导条件下的区域选择性裂解被开发以生成这些不寻常的倍半萜的碱性苯并oc烷环体系。
