Spiro annulation of cage polycycles via Grignard reaction and ring-closing metathesis as key steps

A simple synthetic strategy to C(2)-symmetric bis-spiro-pyrano cage compound 7 involving ring-closing metathesis is reported. The hexacyclic dione 10 was prepared from simple and readily available starting materials such as 1,4-naphthoquinone and cyclopentadiene. The synthesis of an unprecedented oc...
