Unusual regio- and enantioselective [1,2]-Stevens rearrangement of a spirobi[dibenzazepinium] cation

Abstract

Highly symmetric spirobi[dibenzazepinium] cation 3 reacts with P4-t-Bu to form exclusively a ring-expanded tertiary amine; this unusual reactivity can be traced back to the geometry of the ylide.
