  • Chapter 1 describes a general route for making 1,3'-bipyrroles. This work involves intermolecular conjugate displacement using a special Michael acceptor developed in this laboratory. This method is general and enables the construction of highly substituted 1,3'-bipyrroles. The route was first employed to carry out the total synthesis of Marinopyrrole B by previous laboratory members. Chapter 2 describes a new family of routes to substituted phenols, including meta-substituted phenols, which was discovered during studies on the total synthesis of coleophomone B. This work enables efficient aromatization of 2-bromocyclohex-2-en-1-ones to phenols under very mild conditions. The method has extraordinary broad substrate scope and it is transition-metal free. Chapter 3 describes synthetic studies towards the total synthesis of coleophomone B. Several different approaches were explored to construct the challenging tricarbonyl system and the strained 11-membered macrocycle. Although the macrocyclization was not achieved, several advanced precursors for cyclization were synthesized and a new aromatization was discovered.
