title: Synthesis of some thiazoline and thiazolidinone derivatives of 1,4-benzoquinone as potential antimicrobial agents.
abstract: Three novel series of benzoquinone derivatives were synthesized, namely: N-(3-aryl-4-phenylthiazolin-2-ylidene)-N-(1,4-benzoquinone carbonyl) hydrazines; N-(3-aryl-5-carbethoxy-4-methylthiazolin-2-ylidene)-N-(1,4- benzoquinone carbonyl)hydrazine and N-(3-arylthiazolin-4-one-2-ylidene)-N-(1,4- benzoquinone carbonyl) hydrazines. These series were prepared by oxidation of the new hydroquinone precursors. The antimicrobial activity of representative compounds of benzoquinone, as well as of hydroquinone derivatives was studied.
