  A Facile and Selective Synthesis of 2-Alkylamino-4(3H)-quinazolinones

  摘要：

  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.

  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(314)-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. (C) 2011 Elsevier Ltd. All rights reserved.
