Dihydroquinazolinones by Titanocene‐Catalyzed Reductive Radical Addition to Quinazolinones

open access: yesChemistry – A European Journal, EarlyView.
Tri‐ and tetracyclic dihydroquinazolinones or quinazolinones by titanocene catalysis: A highly diastereoselective and efficient reductive radical addition to quinazolinones enables an unprecedented entry to pharmaceutically relevant dihydroquinazolinones by avoiding the interception of radical intermediates prior to the slow radical addition.
