A new dynamic resolution strategy for asymmetric synthesis

Two different and complementary auxiliary based dynamic resolution processes have been developed; the use of crystallisation induced dynamic resolution and/or dynamic kinetic resolution enables the preparation of either enantiomeric product using a single chiral auxiliary as illustrated in the preparation of D or L-alinine derivatives.
