An iodine-catalyzed oxidative C(sp3)-H amination/C-N cleavage of tertiary amines 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 C-N bond formations.

Access to quinazolines: The selective amination of C(sp3)-H bonds 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 C-H bonds is also noteworthy (left: >3:1, right: >99:1). Copyright

Chilin, Adriana,Marzaro, Giovanni,Zanatta, Samuele,Guiotto, Adriano
, p. 3229 - 3231 (2008/02/02)
A rapid and efficient microwave-assisted protocol is described that greatly improves a recent synthetic method developed for quinazoline synthesis. The synthetic protocol is based on the use of cycles of microwave irradiation. The optimization process is reported and the experimental results are compared with those of the conventional synthetic route.

A new synthetic pathway to quinazolines is described. This new method uses hexamethylenetetramine in TFA and potassium ferricyanide in aqueous ethanolic KOH, starting from simple N-protected anilines. The method affords substituted quinazolines with high
New Synthesis of Fused Pyrimidine Derivatives via ortho-(Isocyanomethyl)nitroaromatic Compounds
Ostrowski, Stanislaw
, p. 180 - 187 (2007/10/03)
An efficient synthesis of functionalized fused pyrimidine derivatives from the respective ortho-(isocyanomethyl)nitroarenes is described.Hydrolysis of the isocyano group in the title isonitriles followed by catalytic reduction of the nitro group and subsequent cyclocondensation of the diamine formed with orthoesters leads to the final products.
