本文研究了异莰烷醇两种异构体在Br2-HgO光照条件下的Barton反应, 得到环醚,产率较高。由环醚开环经五步转化选择性地合成了Noji菊醇(Nojigiku alcohol); 环醚可作为β-檀香醇合成中的潜在中间体。

The photo-induced decomposition of endo- and exo-isocamphanyl hypobromites in n-pentane was studied, which resulted in the formation of isomeric cyclic ethers I and II resp. Nojigiku alcohol (III), a monoterpene alcohol isolated from Chrysnathemum japonese, was synthesized from the cyclic ether I via a five-step sequence.
