The initially used chiral precatalyst 1A is converted to the real catalyst 1B through an induction process. An achiral reactant A and substrate B are activated by 1B to form reversibly an intermediate 1C. The chiral environment of 1C induces asymmetric transformation of A and B to the chiral product A–B (R or S) through an intermediate 1D with reproduction of catalyst 1B. The absolute configuration of A–B is ically determined a
