Deskripsi
An unusual rearrangement of spiro cage dione to a trishomocubane derivatives is reported by acid-catalysed rearrangement with the aid of BF3·OEt2 in benzene (solvent) reflux conditions. Here, the molecular structure of cage molecule C19H22O2 (major product) consists of five-membered rings, which adopt an envelope conformation and six-membered rings adopt a chair or boat conformation. The Cremer & Pople puckering parameters of all four six-membered rings are calculated.
