S. Nagai et al., SYNTHESIS AND CENTRAL-NERVOUS-SYSTEM STIMULANT ACTIVITY OF CAMPHOR-1,2,4-BENZOTRIAZINES FUSED WITH 5-MEMBERED AND 6-MEMBERED HETEROCYCLES, Journal of heterocyclic chemistry, 35(2), 1998, pp. 293-296
Novel camphor-1,2,4-triazines fused with imidazole 2-3, thiadiazole 4,
1,2,4-triazole 7, pyrimidine 9-13 and 1,3,5-triazine 14, were synthes
ized starting from 5,6,7,8-tetrahydro-5,8-methano-1,2,4-benzotriazine
1. Evaluation of central nervous system stimulant activity demonstrate
d that the presence of a N-N group at C-3 position of 1,2,4-benzotriaz
ine will be essential for the activity.
