C2-Symmetric bisphosphinites and a bisaminophosphine as new chiral ligands for Pd-catalyzed asymmetric allylic substitution
摘要:
A family of C-2-symmetric bisphosphinites 3, 5, 7, 9 and bisaminophosphine 11 were prepared and were probed in the prototypical reaction system of palladium-catalyzed asymmetric allylic substitution. The highest ee of 86% was achieved by employing ligand 3. (C) 2000 Elsevier Science Ltd. All rights reserved.
