Synthesis & Antifungal Screening of Novel Azetidin-2-ones
A new series of 4-[3-chloro-2-(4-hydroxy-3-methoxybenzyllidene)-4-oxoazetidin-1-yl]amino-N-(substituted) benzenesulfonamide, 4-{3-chloro-2-[5-methoxy-2-nitro-4-(prop-2-en-1-yloxy)benzyllidene]-4-oxoazetidin-1-yl}]amino}-N(substituted)benzenesulfonamide and 4-{3-chloro-2-[4-hydroxy-3-methoxy-5-(prop-2-en-1-yl)benzylidene]-4-oxoazetidin-1-yl}amino}-N-(substituted) benzenesulfonamide were synthesi...
متن کاملSynthesis and Antimicrobial Activities of Some New Azetidin-2-ones and Thiazolidin-4-ones
Various (4-substituted) phenyl-3-β-[(N-benzenesulphonyl/tosyl)-4-(un)substituted anilino]propionylamido-1,3-thiazolidine-4-ones (3a-x) and 1-β-[(N-benzenesulphonyl/tosyl)-4-(un)substituted anilino]-propionylamido-3-chloro-4-(4-substituted)phenyl-azetidin-2-ones (4a-x) have been synthesised by the cyclocondensation of Schiff bases (2a-x) with thioglycolic acid and chloroacetyl chloride, respecti...
متن کاملSynthesis and Pharmacological Evaluation of Azetidin-2-ones and Thiazolidin-4-ones Encompassing Benzothiazole
Various 7-chloro-6-fluoro-2-arylidenylaminobenzo(1,3)thiazole (2a-h) have been synthesized by the condensation of 7-chloro-6-fluoro-2-aminobenzo(1,3)thiazole (1) with different aromatic aldehydes. The Schiff's bases on reaction with acetyl chloride, chloroacetyl chloride and phenyl acetyl chloride yielded 1-(7-chloro-6-fluorobenzothiazol-2-yl)-3,4-substituted-aryl-azetidin-2-ones (3a-x). Simila...
متن کاملSynthesis of novel N-(4-ethoxyphenyl) azetidin-2-ones and their oxidative N-deprotection by ceric ammonium nitrate.
It is shown that the N-(p-ethoxyphenyl) group on beta-lactams can be oxidatively removed by ceric ammonium nitrate in good yield. Fourteen new N-(p-ethoxyphenyl)-2-azetidinones 8a-n were synthesized through standard [2+2] ketene-imine cycloadditions (Staudinger reaction). Treatment of these compounds with ceric ammonium nitrate yielded the N-dearylated 2-azetidinones 9a-n in good to excellent y...
متن کاملEvaluation of the Synthesis and Structure of New Azetidin-2-ones of Ferulic Acid.
AIM To synthesize some new azetidin-2-ones of ferulic acid and to evaluate them from physicochemical and spectral point of view. MATERIAL AND METHODS The synthesis was carried out in several steps: (i) obtaining the ferulic acid chloride; (ii) obtaining the ferulic acid hydrazide with hydrazine hydrate (98%); (iii) condensation of ferulic acid hydrazide with different benzaldehydes (2-hydroxy...
