Convenient Preparation of N-substituted 2-Amino-4H-3,1-benzoxazin-4-ones and 3-Substituted 2,4(1H,3H)-Quinazolinediones

Room temperature of 2-(3-arylureido)benzoic acids (1) and methyl2-(3-alkyl-, or 3-arylureido)-benzoates (2) with concentrated sulfuric acid leads to N-substituted 2-amino-4H-3,1-benzoxazin-4-ones (3) in generally very good yields.The isomeric 3-substitute

Reactions of o-Aminonitriles with Isocyanates. 1. A Two-Step Synthesis of 2,6-Dihydroimidazoquinazolin-5-(3H)one

The reaction of anthranilonitrile with 2-chloroethyl isocyanate yields 2-benzonitrile (6) which, upon heating, or treatment with base, undergoes a double cyclization to form 2,6-dihydroimidazoquinazolin-5-(3H)one (8) in excellent yield.When heated with hydrochloric acid, 6 is converted initially into 2-(2-chloroethylamino)-4H-benzoxazin-4-one (18) and further into 3-(2-chloroethyl)-2,4-(1H,3H)quinazolinedione (15).The acid-catalyzed reaction of 2,3-dihydro-5H-oxazoloquinazolin-5-one (14) with nucleophilic reagents yields 3-substituted 2,4-(1H,3H)quinazolinediones.
