title: Synthetic study of pyrrocidines: first entry to the decahydrofluorene core of pyrrocidines.
abstract: The first synthesis of decahydrofluorene core 4 of pyrrocidines was accomplished. The cis,trans-fused tricyclic ring system was stereoselectively constructed via Diels-Alder reaction using two Danishefsky dienes.
