| Summary: | <p>The primary objective of this research project was to develop a novel protocol for the synthesis of densely functionalized optically enriched indanes through a chiral cation directed 5-endo-trig ring closure. In chapter two, a convergent strategy for the construction of the cyclization precursors is reported, which employs two easily adapted fragments. In chapter three, a range of quaternary ammonium salts are screened to establish the optimal phase-transfer conditions for this system. A variety of substrates were evaluated to probe the scope and limitations of this methodology. Finally, two potential mechanistic pathways for this enigmatic process are outlined and discussed in chapter four.</p>
