- 論文の詳細を見る
Pyrimidine derivatives in which both the 2- and 4-positions are free exhibited site selectivity in their reactions with radicals generated in redox systems. Namely, 6-phenyl-(I), 6-methylpyrimidine (XV), and 5,6,7,8-tetrahydroquinazoline (XVII) reacted with radicals such as RCO, R_2NCO, EtOCO, and CH_2OH to give predominantly the 4-substituted products. Except in the reaction of I with the N, N-dimethylcarbamoyl radical, the formation of the corresponding 2-substituted isomers was not observed.
