Allylic Silanes in [3+2] ...
The [3+2] annulation reactions of allylic silanes are powerful methods for the stereoselective preparation of functionalized five-membered ring carbocycles and heterocycles.
This greater reactivity of the allylamine explains why iridium-catalyzed allylic
substitutions conducted with low concentrations ... the reaction to be conducted
with high concentrations of ammonia and to form the primary allylic amine
selectively.
