enantioselective synthesis of a decahydrofluorene nucleus, the tricyclic core (ABC-ring system) of GKK1032s, novel antimicrobial and anti-tumor agents, was achieved using a highly diastereoselective intramolecular Diels-Alder (IMDA) reaction. The substrate for the IMDA reaction was synthesized through intermolecular Diels-Alder reaction of Kitahara-Danishefsky's diene and an enone derived from enulose to construct
