کاتالیست یک سنتز جدید برای تیواترها توصیف شده است. واکنش الکل ها با آریل، هتروآریل و آلکیل تیو ل ها درحضور 1،3،5- تری آزو- 2،4،6- تری فسفرین-2،2،4،4،6،6 هگزاکلراید ((tapc به عنوان یک کاتالیست موُثر، بازده های خوب تا عالی از تیواترها را حاصل می کند. علاوه براین، واکنش تحت شرایط بدون فلز و بدون حلال پیش می رود، بنابراین یک مکمل جالب برای روش های شناخته شده سنتز تیواترها ارائه می دهد. یک مکانیسم ا...
15 صفحه اولSynthesis and antimicrobial activity of metal complexes from 2-(1’/2’-hydroxynaphthyl)benzoxazoles
Synthesis and antimicrobial activity of new metal [Mg(II), Fe(II), Co(II), Ni(II), Zn(II) and Cd(II)] complexes from 2-(1’/2’-hydroxynaphthyl)benzoxazoles have been described. Some of the metal complexes show significant antifungal activity (MIC <3.12 μg/ml). Further, 2-(1’/2’hydroxynaphthyl)benzoxazoles exhibit excited-state intramolecular proton transfer mechanism that has been studied using ...
متن کاملDAST-promoted Beckmann rearrangement/intramolecular cyclization of acyclic ketoximes: access to 2-oxazolines, benzimidazoles and benzoxazoles.
The first example of DAST-promoted Beckmann rearrangement/intramolecular cyclization of acyclic ketoximes is described. This unique protocol represents a direct and effective pathway to 2-oxazolines, benzimidazoles and benzoxazoles in moderate to good yields.
متن کاملnano-ticl4.sio2 promoted one-pot synthesis of amides or nitriles from aldehydes
this research proposes an efficient and easy procedure for the preparation of amides or nitriles from aldehydes. such materials were prepared via one-pot three component condensation reaction of various aldehydes in the presence of nano-ticl4.sio2 as a catalyst under thermal conditions. all reactions proceeded in high yields and in a moderately short reaction time. meanwhile, oximes were obtain...
متن کاملSynthesis and antimicrobial activity of novel benzoxazoles.
A series of 2-(p-substituted-benzyl)-5-[[4-(p-chloro/fluoro-phenyl)piperazin-1-yl]acetamido]-benzoxazoles were synthesized in need of new compounds for the fight against microbial pathogens. Their structures were elucidated by spectral techniques. These new derivatives, along with previously synthesized 2-(p-substituted-benzyl)-5-substituted-benzoxazoles, were evaluated for their antibacterial ...
