A Stereoselective Organocatalyzed C-Glycosylation of Indole: Implications of Acceptor-Catalyst-Donor Interaction

Org. Chem. Front., 2024, Accepted Manuscript
DOI: 10.1039/D4QO01873G, Research Article
Lihuang Xie, Wenchao Liu, Zhenbo Guo, Qinbo Jiao, Xiaomin Shen, Tianfei Liu, Chunfa Xu
A stereoselective pyridinium hexafluorophosphate-catalyzed C-glycosylation of indole is presented, featuring the plausible formation of a catalyst-acceptor complex and a crucial H-bond between the indole N-H and the oxygen at C6...
