Possible Anthelmintic Agents: Syntheses of Various Imidazoquinazolinone Carbamates

Two of the three possible imidazoquinazolinone-2-carbamates representing angular and linear heterocyclic systems, have been synthesised and evaluated for their anthelmintic activity.During the course of the synthesis of ethyl or methyl 7-alkylimidazoquinazolin-8-one-2-carbamate, it is observed that the reaction of 3-alkyl-7-chloro-6-nitroquinazolin-4-ones with butanol saturated with aq.NH3, furnishes a number of ring-opened products which have been characterised on the basis of elemental analyses, IR, PMR and mass spectral data.The same reaction when carried out with dry NH3, furnishes the desired amino-nitro derivatives.UV and IR spectra of the linear and angular imidazoquinazolinones have also been compared.
