- Abstract
A robust method for the selective labeling of peptides via manganese(I) catalysis was devised to achieve the C‐2 alkenylation of tryptophan containing peptides with 1‐ethynyl‐o‐carboranes. The manganese‐catalyzed C−H activation was accomplished with high catalytic efficiency, and featured low toxicity, high functional group tolerance and excellent E‐stereoselectivity. This approach unravels a promising tool for the assembly of o‐carborane with structurally complex peptides of relevance to applications in boron neutron capture therapy.
The direct incorporation of a carborane moiety into tryptophan‐containing peptides is presented as a sustainable method to access novel potential anti‐cancer and BNCT agents via non‐toxic manganese(I) catalysis. image - Issue Date
