tertiary amines was constructed using a “traceless” linker on a polystyrene resin (REM resin), starting from secondary amines, primary amines, and resin-bound “ammonia”. The methodology is characterized by three essential steps conducted under ambient conditions: (1) coupling of the starting amine (Michael addition) to the resin, (2) activation (quaternization), and (3) cleavage of the product amine (Hofmann
