An autoxidation study of C2 substituted pyrimidine amino reductones
Three pyrimidine derivatives (8a-c), differing from isouramil and divicine at C2, have been synthesized and their autoxidation rates measured spectrophotometrically. The autoxidation rates of all five pyrimidines (8a-c, isouramil and divicine) were correl
SUBSTITUTED PYRIMIDINES, PROCESS FOR THEIR PRODUCTION AND THEIR USE AS EFFECTIVE ABSORBENTS OF UV IRRADIATION
The present invention discloses substituted pyrimidines, processes for their synthesis and their use as effective sun-protecting agents either alone or in combination with other known sun-protecting agents.
