Precolibactin 886 is a complex microbiome-derived metabolite implicated in colorectal cancer and produced by the clb gene cluster. A chemical synthesis and analysis of precolibactin 886 is reported which shows that its biosynthetic precursor degrades to other known clb metabolites. The data also provide insights into the structures and reactivity of advanced clb products.
