Chemo- and site-selective derivatizations of natural products enabling biological studies

The direct chemo- and site-selective modification of native bioactive natural products (NP) for structure–activity relationship (SAR) studies and cellular probe synthesis has recently begun to be addressed (FG = functional group). This review highlights selected recent examples of these functionalization strategies, including those that simultaneously introduce a linker and reactive group (gray structure) for subsequent conjugation to reporter tags.
