A mechanistic study of chiral manganese porphyrin-catalyzed enantioselective C–H hydroxylation reaction

Dalton Trans., 2024, Advance Article
DOI: 10.1039/D4DT02452D, Paper
Jing-Kun Gao, Wandong Chen, Junjie Tai, Zhengwei Chen, Hang Liu, Yuxin Du, Yiting Jiang, Yuanbin She, Yun-Fang Yang
This study uses DFT to explain the enantioselectivity of C–H hydroxylation by a chiral manganese porphyrin. A two-point hydrogen bonding favors pro-(S) C–H bond abstraction by 1.9 kcal mol−1, leading to (S)-hydroxylated products.
