title: One-pot cascade approach to phenanthridine-fused quinazoliniminiums from heteroenyne-allenes.
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.
