摘要

A series of 4-arylidene-2-methyloxazol-5-ones 1 were condensed with thiosemi-carbazide to yield 6-arylmethyl-3-mercapto-l,2,4-triazin-5-ones 2.The resulting mercapto triazinones 2 were condensed with monochloroacetic acid and 5-aryl-furan-2-carboxaldehydes 3 in a one-pot three-component reaction in the presence of acetic anhydride,acetic acid,and sodium acetate to yield 4-substituted-5-oxo-7-(5-aryl-2-furfurylidene)-l,2,4-triazino[3,4-b]-thiazol-6-ones 4.Some of the newly synthesized compounds were tested for their antibacterial activity against Gram (+)ve and Gram ( - )ve bacteria.The results of such studies are discussed in this paper.
