A facile one-pot synthetic route for preparing the novel benzofused tricyclic skeleton of 1,2,2a,8b-tetrahydrocyclobuta[a]naphthalenes 5 is developed. The route was realized by a NaH-mediated tandem aldol condensation/olefin migration/electrocyclization of o-allylbenzaldehydes 1 with cinnamyl sulfones 3 in good yields.
开发了一种容易的一锅合成路线,以制备新型的1,2,2a,8b-四氢环丁[ a ]萘5苯并稠合的三环骨架。该途径是通过NaH介导的串联羟醛缩合/烯烃迁移/邻烯丙基甲醛1与肉桂基砜3的电环化以高收率实现的。
