We demonstrate the direct use of benzylic alcohols for a multicomponent reaction of readily available isatoic anhydrides with amines in water, which is a synthetic route for the direct construction of a series of 2-aryl quinazolinones. This one-pot synthetic method involves the dehydrative N-benzylation of in situ generated anthranilamides followed by an amide-directed benzylic C−H amination process

A new, selective Ru(II)-catalyzed alkynylation reaction of isoquinolones, quinazolones and phthalazinones with readily available bromoalkynes has been developed. This reaction enables the selective construction of a new C(sp2)-C(sp) bond through C—Hactivation and C—Br functionalization, and offers an effective and selective route to synthesizing highly valuable alkynylated isoquinolone, quinazolone
A novel catalytic system is reported for the construction of quinazolinones via the carbon-supported acid-catalyzed cascade coupling of isatoic anhydrides with amides and aldehydes. Subsequent selective hydrosilylation of the quinazolinones using a hydrogen-transfer strategy was also explored to provide dihydroquinazolines with structural diversity. The developed methodology proceeds with a broad substrate
