New P, N, N’, P’Ligands Based on Carbohydrates for Highly Enantioselective Pd-Catalysed Allylic Substitution

摘要: The industrial application of asymmetric catalysis to the synthesis of enantiopure substances is a growing area of interest. 1 Aiming to contribute to this flourishing field, we have focussed our studies on the synthesis of a new class of chiral ligands, prepared by modification of the common and inexpensive mannose (I) and glucose (II).
