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.
Regioselective C‐2‐H benzylation of quinazolin‐4(3H)‐ones with N‐tosylhydrazones in a ligand dependent copper system was studied. An array of substituted quinazolin‐4(3H)‐ones were coupled effectively with a wide variety of N‐tosylhydrazones derived from aryl ketones to afford the alkylated products in moderate to good yields. This is a useful, time‐efficient, and scalable procedure for the construction

Structure-activityrelationship and crystallographic data revealed that quinazolinone-containing fragments flip between two distinct modes of binding to activin receptor-like kinase-2 (ALK2). We explored both bindingmodes to discover potent inhibitors and characterized the chemical modifications that triggered the flip in bindingmode. We report kinase selectivity and demonstrate that compounds of
