Non-heme manganese complexes of C1-symmetric N4 ligands: Synthesis, characterization and asymmetric epoxidations of α,β-enones
摘要:
A series of proline-derived C-1-symmetric chiral tetradentate N ligands and their manganese complexes have been synthesized and characterized. Their applications in enantioselective epoxidations of alpha,beta-enones were explored reaching good yields and up to 71% ee at room temperature. (C) 2012 Elsevier B. V. All rights reserved.

A series of C1-symmetric bench-stable stereogenic-at-iron complexes comprising a linear, tetradentate ligand scaffold are introduced. The possibility of lowering the overall symmetry is scrutinized for an enantioselective ring-contraction of isoxazoles to furnish chiral 2H-azirines under open-flask conditions with the products serving as useful building blocks to access α-disubstituted α-amino acid
