Abstract
A facile C-H amination of quinazoline employing N-fluorobenzenesulfonimide (NFSI) as the amination source has been disclosed in the absence of any metal, oxidant or additive. The methodology shows a board range of quinazolines with different functional groups in moderate to good yields up to 87 %. Furthermore, gram-scale reaction, desulfonylation to amine and synthesis of pharmaceutical intermediate were also investigated, which demonstrates potential applications in medicinal chemistry. A plausible amination mechanism is proposed via F+ transfer accompanied by the removal of one molecule of PhSO2F. DFT studies with experimental work suggest that the mechanism via F+ transfer is more favorable than the free radical one.

Abstract
This review summarizes the transition metal-catalyzed direct C–H functionalization
of quinazolinones and quinazolines through C-C, C-N and C-O bond formations. It focuses
mainly on the C-H (sp<sup>2</sup> or sp<sup>3</sup>) bond arylation, amination, sulfamidation, acetoxylation,
halogenation, annulation of quinazolinones and quinazolines. This review illustrates the scope
of C-H activation and functionalization of various quinazolinone and quinazoline derivatives.
