It has been found that under the action of hydrazides of carboxylic acids, 2-iminocoumarin-3-carboxamides are recyclized to N(1)-acylamidrazones of coumarin-3-carboxylic acids. The use of N(1)-acylamidrazones is proposed as a simple and effective mea

The reaction of 5,6-diamino-1,3-dimethyluracil with 1,3-diaryl-2,3-dibromopropan-1-ones gave β-(5-amino-6-imino-1,3-dimethyluracil)chalcones, and conditions for their cyclocondensation to pyrimidinodiazepines were found. For substantiation of the re
