tert‐Butyl hydroperoxide (TBHP) served as the methylsourceunder metal‐free aerobicconditions in the oxidativeamination of a C(sp3)–Hbond to provide quinazolin‐4(3H)‐one and quinazoline derivatives.

An iodine-catalyzedoxidative C(sp3)–H amination/C–N cleavage of tertiaryamines couducted under an oxygen atmosphere has been developed and affords a route to quinazolines and quinazolinones in good to excellent yields via a domino ring annulation. The method is metal-free, peroxide-free, and operationally simple to implement with a wide scope of substrates and represents a new avenue for multiple

A copper-catalysed three-component reaction for constructing a series of quinazoline derivatives has been developed. In this system, solvents act as the reactants and different functional groups are well tolerated to obtain corresponding products in moderate to good yields.

The selectiveamination of C(sp3)Hbonds adjacent to nitrogen or oxygen atoms of N‐alkylamides, ethers, or alcohols with ortho‐carbonyl‐substituted anilines constitutes the first step in a tandem annulation that leads to quinazolines in good to excellent yields (see scheme; NIS=N‐Iodosuccinimide, TBHP=tert‐butyl hydroperoxide). The selectivity of the amination of primary and secondary CHbonds is
