Taylor and Patel describe a quinazoline synthesis (Scheme 93) transforming the iminophosphorane of anthranonitrile with isocyanate to car-bodiimide 254. Addition of ammonia in tetrahydrofuran (THF) leads to guanidine 255, which affords with the adjacent nitrile function quinazoline derivatives 256 (91JHC1857). [Pg.213]

Other examples this type of quinazoline synthesis include the formation of the thione analog 752, by displacement of bromine from thiourea 751 <2003ARK(x)434>, and the imino compound 754, which could be formed by heating the guanidine derivative 753 in DMF, without the need for any added base <2005RJ01071>. [Pg.205]

The striking improvement in the Niementowski quinazoline synthesis [156, 157] has been fulfilled using microwave irradiation by Besson et al. [158,159] (Scheme 7). Using microwave irradiation and/or Appel s salt, new efficient routes to various substituted and fused quinazolines have been developed by Besson et al. [158,159] and also by others [ 160,161]. [Pg.125]
