Abstract
A one-pot
cascade method to obtain functionalized phenanthridine-fused
quinazoliniminiums from a variety of heteroenyne-allenes is described.
This protocol involves formation of C–N and C–C bonds
in a single step in the presence of a Lewis acid and trace water to
afford pentacyclic title compounds in moderate to good yields
