摘要：

A new synthetic approach to the bicyclo[3.3.1]nonane system, a common structure in a number of polyisoprenylated phloroglucinol derivatives (phloroglucins), has been developed. The key step in our approach is a 'one-pot' procedure of two successive reactions, the intramolecular cyclopropanation reaction which affords the tricyclo[4.4.0.0(5.7)]dec-2-ene derivative and its methoxy group directed regioselective ring-opening reaction mediated by ZnCl2, producing the desired bicyclo[3.3.1]nonane as the sole product.
