Potassium carbonate mediated unusual transformation of 2,3-dihydroquinazolinone via cascade reaction
摘要:
An unusual potassium carbonate mediated transformation of 2,3-dihydroquinazolinone by a one-pot operation is reported under mild conditions. In addition, it is interesting to report the regioselective transformation of 3-(2-bromophenyl)-2-isopropyl-2,3-dihydroquinazolin-4(1H)-one from compound 16. (C) 2013 Elsevier Ltd.

A highly efficient synthesis of phenanthridine/benzoxazine‐fused quinazolinones by ligand‐free palladium‐catalyzed intramolecular CHbondactivation under mild conditions has been developed. The CC coupling provides the corresponding N‐fused polycyclic heterocycles in good to excellent yields and with wide functional group tolerance.
