A density functional theory study on mechanism and substituent effects of a base-free and catalyst-free synthesis of functionalized dihydrobenzoxazoles

The reaction mechanism and the substituent effects of a base-free and catalyst-free synthesis of functionalized dihydrobenzoxazole have been investigated in detail by using the density functional theory (DFT) method. The calculated results reveal that the whole reaction should occur through three processes, and the initial intramolecular nucleophilic attack reaction is the rate-determining step. The possibility to afford crossover reaction products has been carefully excluded based on the extremely high barrier, which is well-consistent with the experimental results that the crossover products cannot be observed. The substituent effects have been studied through exploring the correlation of the experimental yields and the theoretically predicted barriers, which proves that the more electron-donating substituents of the imine should be more beneficial to the occurrence of the reaction.

Unexpected Rearrangement Reaction and Synthesis of Benzoxazoles

Novel series of rearrangement reactions were herein reported that enable access to a variety of unique 2-aryl-3-(3′-oxobutenyl)-benzoxazole compounds 6a similar to 6f from 2-aminophenol, aromatic aldehyde and 3-butyn-2-one as materials by nucleophilic conjugate addition, dehydration and rearrangement reactions and intramolecular cyclization in the presence of a catalytic amount of CH3COOH in CH2Cl2 at ambient temperature. On the basis of products and intermediate products, a series of possible mechanism was presented and theoretically verified by density functional theory (DFT) method at B3LYP/6-31G (d,p) level from both molecular energy and atomic charge in Gaussian 03 package. The results show that the theory and experiment consistently explain the rationality of the reaction mechanism. The mechanism of rearrangement provides a basis for further study of this type of reaction. The advantage of this method is that a novel structure of benzoxazole derivative was synthesized successfully via a series of rearrangement reactions. Therefore, this method can be used as an attractive strategy for practical synthesis of nitrogen heterocyclic compounds.

Thiosemicarbazonate complexes with affinity for amyloid-beta fibers: synthesis, characterization and biological studies

Aim: Obtain radioimages of amyloid-beta fibers using Tc-99m-complexes. Methodology: Tridentate thiosemicarbazone and thiocarbonohydrazone ligands containing fragments (stilbene, azobenzene, benzothiazole or benzoxazole) with affinity for amyloid-beta fibers and its Re(I) complexes have been prepared. The molecular structures of several ligands and complexes were determined by x-ray diffraction. Binding affinity studies toward A beta 1- 42 fibers were performed for the ligands and Re(I) complexes. The ability of formation of some Tc-99m(I) complexes, their biodistribution and in vivo stability have been established. Results & conclusion: Complexes of stilbene and benzothiazole thiosemicarbazonates show similar affinity for amyloid-beta fibers to the free ligand. These Tc-99m complexes present a reasonable in vivo stability and a low capability to cross the blood-brain barrier although not sufficient to brain amyloid imaging.

Synthesis and Evaluation of Antibacterial and Anticancer Activities of Some New Benzoxazole-Piperazine-1,2,3-Triazoles

Some new 2-((4-((1-aryl-1H-1,2,3-triazol-4-yl)methyl)piperazin-1-yl)methyl)benzo[d] oxazoles (4a-j) were synthesized through Cu(I) catalyzed [3+2] cycloaddition reaction between 2-((4-(prop-2-yn-1-yl)piperazin-1-yl)methyl)benzo[d]oxazole (3) and several aryl azides. The in vitro anticancer and antibacterial activities evaluation revealed that compounds 4g, 4f, and 4d possess good activities, whereas the remaining compounds are associated with moderate to low activities.
