摘要: The new regioisomer 7-methyl-pyrazolo[4,5-e] [1,2,4]thiadiazine nucleus (5) was synthesized, and its novel mono-N₂-or N₄-substituted pyrazolo[4,5-e] [1,2,4]thiadiazines (6, 7) were regioselectively prepared by deprotonation of NN₂ or/and N₄ atoms with different molar ratio of NaH and alkyl halides. Anti-HIV-1 screening tests showed some compounds to be potent as HIV-1 nonnucleoside reverse transcriptase inhibitors (HIV-1 NNRTIs).
