A series of new pyrazolopyrimidinederivativescontainingsulfuratom 5 has been designed and synthesized by treatment of carbodiimide 3, which came from iminophosphorane 2 undergoing a aza-Wittig reaction with phenyl ioscyanate, with alkylamine. The structures of compounds 5 were confirmed by 1H NMR, IR, EI-mass spectroscopy, and elemental analysis. The results of preliminary bioassay indicate that
