6-endo-dig cyclization to fashion its tetracyclic indolenine core, as well as the need to develop what could be considered a reversed polarity aza-Prinscyclization to deliver its tertiary allylic alcohol and final cage structure. The power of the latter design element is highlighted by several failures in achieving similar functional group patterning through more traditional aza-Prins and Mannich
