S. Nagai et al., SYNTHESIS AND CENTRAL-NERVOUS-SYSTEM STIMULANT ACTIVITY OF CAMPHOR-1,2,4-TRIAZINES FUSED WITH 1,2,4-TRIAZOLE, TETRAZOLE AND 1,2,4-TRIAZINE, Heterocycles, 44, 1997, pp. 117-120
Camphor-1,2,4-triazines fused with 1,2,4-triazole(3-9), tetrazole(10)
and 1,2,4-triazine(11), were synthesized starting with (5R, 7,8-tetrah
ydro-5,8-methano-1,2,4-benzotriazine(2). Compounds (2,3 and 10) showed
central nervous system (CNS) stimulant activities.
