Although the widespread usage of aza-pinacol and aza-semipinacol rearrangements as
synthetic methods has not been found, these synthetic transformations offer novel
tactics for the preparation of nitrogen-containing heterocycles and natural alkaloids.
Herein, we briefly discuss the most recent developments in this area and present our
strategy based on aza-pinacol rearrangements for the synthesis of indolines and indolenines.
