An autoxidation study of C2 substituted pyrimidine amino reductones
摘要:
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 correlated with sigma(+)(p) values (rho=-1.28, r(2)=0.949). (c) 2006 Published by Elsevier Ltd.
