An efficient synthesis and biological activity of substituted p-benzoquinones
摘要:
An efficient synthesis of 2,5 -diarylamino-3,6-dichloro-1,4-benzoquinone derivatives has been achieved by condensing mono substituted anilines with tetrachloro-p-benzoquinone in presence of fused sodium acetate as condensing agent under microwave irradiation without any solvent. All the synthesized compounds were tested for their antibacterial and antitumour activity using standard drugs. (c) 2006 Elsevier Ltd.. All rights reserved.

A number of substituted 6,13-dihalogenotriphenodioxazines have been synthesised (a) by condensing halogeno-p-benzoquinones with arylamines followed by cyclisation of the resulting bisarylamino-quinones with benzoyl chloride in nitrobenzene and (b) by condensing halogeno-p-benzoquinones with o-aminophenols in the presence of anhydrous sodium acetate in an alcoholic medium. A few triphenodithiazines
