The first example of the stereoselective synthesis of 7 β-carbamoyl-4,5 α-epoxymorphinan via a novel and reactive γ-lactone

7 β-Carbamoyl-4,5 α-epoxymorphinans 5 were stereoselectively synthesized from the 7 α-carboxylate intermediate 3 in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and amines under reflux conditions in mesitylene via a novel and reactive γ-lacton
