as antimicrobial agent, 31 novel chloropyrrole derivatives of aroyl hydrazones and chalcones incorporating common pharmacophore of pyoluteorin derivatives were synthesized. Antimicrobial activity of the synthesized compounds was evaluated using broth dilution technique. Based on biological evaluation data it was observed that activity increases as the number of chlorines on pyrrole core increases. Few

A series of mono- to hexachlorinated BODIPYdyes have been prepared in good to excellent yields through the use of N-chlorosuccinimide as an inexpensive halogenating reagent. This library of chlorinated dyes allowed analysis in detail, from the experimental and theoretical points of view, of the dependency of the photophysical and optical properties of the dyes on the number and positions of the chlorine

Abstract: A structurally simple and reactive chlorinatingreagent,N-chloro-N-methoxybenzenesulfonamide, was conveniently and economically prepared in high yield. 1,3-Diketones, β-keto esters, benzoyl trifluoroacetones, phenols, anisoles, heteroarenes andaromatic amines were chlorinated with it, obtaining chlorinated products in good to high yields.
(±)-chlorizidine A has been achieved in 10 steps. Pd-catalyzed decarboxylative coupling and late-stage oxidation were utilized to construct the 5H-pyrrolo[2,1-a]isoindol-5-one scaffold. Samarium(II) iodide mediated Reformatsky reaction and intramolecular Mitsunobu reactions were efficiently applied for the synthesis of the 2,3-dihydropyrrolizine ring system. Chlorizidine A is highly prone to degradation; hence, methyl-protected
甲基保护的(±)-氯联苯胺A的第一个全合成已通过10个步骤完成。钯催化的脱羧偶联和后期氧化被用来构建5 H-吡咯并[2,1 - a ] isoindol-5-one支架。碘化Sa(II)介导的Reformatsky反应和分子内Mitsunobu反应有效地用于合成2,3-二氢吡咯烷嗪环系统。氯唑烷A极易降解;因此,制备了甲基保护的(±)-氯联苯胺A。
