摘要
The total synthesis of Microcin SF608 is reported. Access to the octahydroindole core structure of Microcin SF608 relies on the TMSOTf/NEt3-mediated opening of an oxabicyclic ring system. Additional highlights of the synthetic strategy that is reported include a highly regioselective epoxide reduction and photolytic excision of a 3 alcohol.
