Abstract
Chiral L2/Z*-type ligands featuring a bisoxazoline framework have been successfully synthesized and applied in asymmetric allylic alkylation. These ligands, designed based on an oxazoline skeleton and derived from chiral amino acid derivatives, incorporate antimony and bismuth as Z-type ligands. Ligands with bulky, electron-withdrawing groups on antimony and bismuth showed enhanced catalytic performance. This research highlights the potential of these novel chiral L2/Z*-type ligands to improve asymmetric catalysis.
期刊介绍：
SYNLETT is an international journal reporting research results and current trends in chemical synthesis in short personalized reviews and preliminary communications. It covers all fields of scientific endeavor that involve organic synthesis, including catalysis, organometallic, medicinal, biological, and photochemistry, but also related disciplines and offers the possibility to publish scientific primary data.
