9-diene-8,14-dione 7 and tetracyclo[10.2.2.01,10027]hexadeca- 2(7),9-diene-8,13-dione 8 have been prepared through acid-catalysed intramolecular cyclisation of the diazomethyl ketones 19 and 25 respectively. The compound 7 is a skeletal representative of several tetracyclic diterpenes.
四环[10.3.1.0。1,10。0. 2.7 ] hexadeca-2(7),9-diene-8,14-dione 7和四环[10.2.2.0 1,10 0 27 ] hexadeca-2(7),9-diene-8,13-dione 8通过分别对重氮甲基酮19和25进行酸催化的分子内环化反应制备了α-己内酰胺。化合物7是几种四环二萜的骨架代表。
