Understanding the mechanism of [3 + 2] cycloaddition reaction of benzoisothiazole-2,2-dioxide-3-ylidene with nitrones

A theoretical investigation was carried out on the mechanism and regioselectivity of the [3 + 2] cycloaddition (32CA) reaction of benzoisothiazole-2,2-dioxide-3-ylidene with nitrone using Molecular Electron Density Theory through DFT calculations at B3LYP and wB97xD functionals with 6-31G(d,p) basis set in the gas phase and toluene. Hard and soft acids and bases principle, Parr functions, as well as potential energy surface analysis were utilized for studying the regio- and stereoselectivity of this reaction, and the obtained results are consistent with the experimental observations. The electron localization function analysis of the nitrone shows that there is a double bond between N and C in the absence of any carbenoid or pseudoradical center. Therefore, a zwitterionic structure for nitrone 2 can be suggested, expected that its 32CA reaction is zw-type. The noncovalent interactions topological analysis shows that the first sigma bond has been formed before reaching the TS, which is in line with a two-stage one-step mechanism.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. 272-16-2, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 272-16-2, in my other articles.

Novel urea and thiourea derivatives of thiazole-glutamic acid conjugate as potential inhibitors of microbes and fungi

Since discovery and development of effective as well as safe drugs has brought a progressive era in human healthcare that is accompanied by the appearance of drug resistant bacterial strains, there is constant need of new antibacterial agent having novel mechanisms of action to act against the harmful pathogens. In the present study, several N-terminal substituted urea/thiourea derivatives were synthesized by the reaction of glutamic acid and 3-(1-piperazinyl)-1,2-benzisothiazole with various substituted phenyl isocyanates/isothiocyanates. Elemental analysis, IR, 1H NMR, 13C NMR and mass spectral data confirmed the structure of the newly synthesized compounds. The derivatives were investigated for their antibacterial and antifungal activities against various pathogens of human origin by agar well diffusion method and microdilution method. The preliminary antimicrobial bioassay reveals that the compounds containing fluoro and bromo as substituents showed promising antimicrobial activity. Pleiades Publishing, Ltd., 2013.
