4-Substituted pentacyclo [5.3.0.02,5.03,9.04,8]decan-6-one derivatives 2a and b undergo a novel acid-or Ag+-catalysed rearrangement to the hitherto unknown pentacyclo[4.4.0.02,10.03,8.05,7]decane ring system 3a and b. The structure of compound 3a was established by X-ray crystallographic analysis.
4-取代的五环[5.3.0.0 2,5 .0 3,9 .0 4,8 ] decan-6-一衍生物2a和b经历新的酸或Ag +催化重排,形成迄今未知的五环[4.4。 0.0 2,10 .0 3,8 .0 5,7 ]癸环系统3a和b。通过X射线晶体学分析确定化合物3a的结构。
