One-Pot Cascade Approach to Phenanthridine-Fused Quinazoliniminiums from Heteroenyne-Allenes
摘要:
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.
