Synthesis and Antimicrobial Activities of Some Heterocyclic Systems from 2-Furoyl Isothiocyanate

2-Furoyl isothiocyanate (1) is used as a building block in synthesizing different heterocyclic systems of anticipated biological activities. Thus, isothiocyanate 1 was reacted with different nucleophilic reagents to produce five- and six-membered heterocyclic systems such as 1,2,4-triazoline, thiadiazolidine, quinazoline, benzothiazole, benzoxazole, benzimidazole, thiazolidine, and imidazolidine. The structures of all the synthesized compounds were confirmed by microanalytical and spectral data. The antimicrobial activity of some of the synthesized compounds was tested.
