Abstract:  The bicyclo[5.3.0]decane (hydroazulene) ring system is present in many natural products. A metathesis approach provided rapid access to the guaiane sesquiterpene (-)-englerin A (1) that shows a potent and highly selective action against renal cancer cell lines.1 Ongoing work towards several other guaianes will be discussed as well.2

The diterpene kempene-2 (2) incorporates the hydroazulene moiety as part of the complex tetracyclic kempane framework. A domino metathesis was the key step in the first enantioselective total synthesis of this kempane and structurally related compounds isolated from the soldier defense secretion of higher termites.2
