Synthesis of the title ring system by a sequential intermolecular nucleophilic displacement and intramolecular 'conjugate' addition has been achieved both as a one pot and as a stepwise procedure; an X-ray structure determination has been carried out to distinguish between the possible isomeric structures 8c-I and 8c-II.
