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.

the construction of 2-alkyl substituted quinazolin-4(3H)-ones and benzo[4,5]imidazo[1,2-c]quinazolines using trialkylamines as carbon synthons has been developed. Some of the notable features of this methodology include the synthesis of potent central nervous system depressants (CNS) drug molecules methaqualone (3 la), mecloqualone (3 pa) and gram-scale synthesis.
