Studies Toward The Total Synthesis Of Subincanadine E, Corinne Marie Sadlowski
Graduate College Dissertations and Theses
Progress towards a concise total synthesis of subincanadine E is reported. This natural product was first isolated from the Picralima nitida cell suspension culture line in 1982 under the name pericine and later in 2002 from Aspidosperma subincanum as subincanadine E. It is the most potent compound of its class with in vitro cytotoxicity against both murine lymphoma L1210 and human epidermoid carcinoma KB cells (LD50, 0.3 ug/mL and 4.4 ug/mL, respectively) and was found to be six times more potent than codeine as an opiate agonist in a 3H-naloxone binding study (IC50, 0.6 umol/L).
The first-generation synthesis produced an …
