Transient reaction steps often remain elusive to conventional NMR detection. Using hyperpolarized dDNP-NMR with signal enhancements over 30 000, we clarified pathways in biomass upgrading. Both furfural and a lactone deriving from were using PEG-400/trityl matrix at natural isotope abundance. Hyperpolarization allowed the detection of species by tracking protonated sites that undergo significant chemical shift changes. Combined careful choice decoupling scheme, revealed undergoes Baeyer-Villiger oxidation, while epoxidation.
