Site-selective C-H hydroxylation of pentacyclic triterpenoids directed by transient chiral pyridine-imino groups
Pentacyclic triterpenoids (PTs) constitute one of the biggest families of natural products, many with higher oxidation state at the D/E rings possess a wide spectrum of biological activties but are poorly accessible. Here we report a site-selective C-H hydroxylation at the D/E rings of PTs paving a...
