title: Exploitation of cyclopropane ring-cleavage reactions for the rapid assembly of tetracyclic frameworks related to gibberellins.
abstract: [Structure: see text] The readily available hexahydrofluorene 5 has been elaborated over six steps, including three involving cyclopropane ring-cleavage reactions, into compound 12 which incorporates the carbocyclic framework associated with gibberellins.
