Liang, Yi,Ding, Ming-Wu,Liu, Zhao-Jie,Liu, Xiao-Peng
, p. 2843 - 2848 (2003)
The carbodiimides 2, obtained from aza-Wittig reactions of iminophosphorane 1 with aromatic isocyanates, reacted with aliphatic primary amines to give mainly 2-alkylamino-4(3H)-quinazolinones 4 with unusual selectivity.
Solid-phase synthesis of 3H-Quinazolin-4-ones based on an aza Wittig-mediated annulation strategy
Villalgordo, José M.,Obrecht, Daniel,Chucholowsky, Alexander
, p. 1405 - 1407 (1998)
Aza Wittig-mediated annulation provides a highly efficient and straightforward strategy for the parallel synthesis of 3H-quinazolin-4-ones on solid support. The products were recovered in good yields and exhibited excellent purities.
RE[N(SiMe3)2]3-Catalyzed Guanylation/Cyclization of Amino Acid Esters and Carbodiimides
Lu, Chengrong,Gong, Chao,Zhao, Bei,Hu, Lijuan,Yao, Yingming
, p. 1154 - 1159 (2018/02/10)
The example of rare-earth metal-catalyzed guanylation/cyclization of amino acid esters and carbodiimides is well-established, forming 4(3H)-2-alkylaminoquinazolinones in 65-96% yields. The rare-earth metal amides RE[N(TMS)2]3 (RE = Y, Yb, Nd, Sm, La; TMS = SiMe3) showed high activities, and La[N(TMS)2]3 performed best for a wide scope of the substrates.
Molybdenum-mediated synthesis of quinazolin-4(3H)-ones via cyclocarbonylation using microwave irradiation
Roberts, Bryan,Liptrot, David,Luker, Tim,Stocks, Michael J.,Barber, Catherine,Webb, Nicola,Dods, Robert,Martin, Barrie
supporting information; experimental part, p. 3793 - 3796 (2011/08/06)
A new, efficient and practical synthesis of quinazolin-4(3H)-ones is reported via molybdenum-mediated cyclocarbonylation using microwave irradiation. These methods allow access to a wide range of quinazolin-4(3H)-ones in reasonable yields without the need for gaseous carbon monoxide and palladium catalysts. A range of reactions illustrating the wide scope of this chemistry was carried out and all proceeded in reasonable yields.
Synthesis of Some Fused-ring Derivatives from 4(3H)-Quinazolone
Talukdar, P. B.,Sengupta, S. K.,Datta, A. K.
, p. 638 - 640 (2007/10/02)
A few more well-defined mesoionic thiazoloquinazolones have been synthesized and their properties recorded.Attempts to build-up analogous fused-ring mesoionic systems via 2-chloro-3-phenyl-4-quinazolone have not been successful.Several new triazolo
