Three alternativesynthetic entries into Johnson's classic synthesis of rac-progesterone are presented in this manuscript. ent-Progesterone, the non-natural enantiomer of progesterone, has recently been identified as a potential alternative to progesterone for investigations into possible prevention and treatment of traumatic brain injury (TBI). Difficulties in accessing ent-progesterone in large quantities
