- FACTORS AFFECTING CYCLIZATION OF N-SUBSTITUTED 2-ACYLAMINO-3,5-DIBROMOBENZAMIDES TO 2,3-DISUBSTITUTED 6,8-DIBROMOQUINAZOLIN-4-ONES
-
The factors affecting cyclization of N-substituted 2-acetylamino-3,5-dibromobenzamide (6a-c) to the corresponding 2,3-disubstituted 6,8-dibromoquinazolin-4-ones (7a-c) were studied.The cyclization process was found to depend on basicity and polarity of th

- Reactions with 3,1-Benzoxazin-4-ones. 3. Reactions of 6,8-Dibromo-2-methyl-3,1-benzoxazin-4-ones with Amines
-
We observed that the reactions of 6,8-dibromo-2-methyl-3,1-benzoxazin-4-one, 5, with primary amines occurs very slowly in ethanol solution at room temperature and that the product is usually the corresponding 2-acetamido-3,5-dibromobenzamide, 6.These resu
