Facile access to a benzoazepinoquinazolinone via a free radical cyclization

Shawakfeh, Khaled Q.,Ishtaiwi, Zakariyya N.,Al-Said, Naim H.

, p. 1329 - 1331 (2014/03/21)

An efficient synthetic protocol based on a free-radical cascade reaction via 6-exo-trig and 7-endo-trig cyclization processes is described for a new substituted benzoazepinoquinazolinone system which could in principle be used to form the cyclopropanequinone system found in duocarmycins.
