The direct conversion of allylic C-H bonds to C-C bonds is a problem with few solutions. We are currently investigating possible solutions to this problem utilizing various rhodium catalysts to induce C-H activation and hydroalkylation of these allylic C-H bonds towards the synthesis of pyrrolizidinone alkaloids. Once optimal reaction conditions are established, these methods will be applied to the total synthesis of natural products, such as UCS1025A, a known telomerase inhibitor.
