-
Two cyclopropyl spiro thiobarbiturs with rigid configurations were designed,synthesized and characterized by IR and NMR.The difference in the chemical shift of N-H between compounds 1a and 1b was observed.The rigid structure was also proved by the relation between the proton (-CH2-) in the cyclopropane ring and the nearest proton (N-H) in the bartitur ring on 1H-1H COSY map due to the shielding effect of the two rings.The anticonvulsion activities of the two novel compounds 1a and 1b were also tested and the restrain ratio was 50% and 70% respectively.
