TS-1 zeolite as a Lewis acid catalyst for solvent-free one-pot synthesis of 1,3-thiazolidin-4-ones

Titanium silicate (TS-1) zeolite heterogeneous catalyst is synthesized by the hydrothermally discontinuous method and is characterized by using XRD, SEM, TEM, and NH3-TPD techniques. The catalytic activity of the TS-1 type zeolite was tested for one-pot solvent-free synthesis of 1,3-thiazolidine-4-ones. The present technique illustrates many benefits, including eco-friendly reaction conditions, environmentally helpful, short response time, simplicity, straightforward separatation, catalyst reusability and high yields of the products. Furthermore, the catalyst was utilized for four recycle reactions and it has been found that the catalyst shows consistent chemical process activity. [GRAPHICS] .

Novel thiazolidines: Synthesis, antiproliferative properties and 2D-QSAR studies

A series of N-substituted (Z)-2-imino-(5Z)-ylidene thiazolidines/thiazolidin-4-ones were synthesized and their antiproliferative activities against colon (HCT-116) and breast (MCF7) cancer cell lines were evaluated utilizing an MTT growth assay. A 2D-QSAR investigation was conducted to probe and validate the obtained antiproliferative properties for the thiazolidine derivatives. The majority of the thiazolidines exhibit higher potency against a colon cancer cell line relative to the standard reference. The p-halophenylimino p-anisylidene derivatives exhibited the highest anti-proliferative activity against HCT116 relative to control (IC50 = 8.9-10.0 mu M compared to 20.4 mu M observed for 5-fluorouracil as positive control). An X-ray study confirmed the Z, Z’-configurations for two examples of the synthesized compounds.

Steric Enforcement about One Thiolate Donor Leads to New Oxidation Chemistry in a NiSOD Model Complex

Ni-containing superoxide dismutase (NiSOD) represents an unusual, member of the SOD family due to the presence of oxygen-sensitive Ni Says bonds at its active site. Reported in this account is the synthesis and properties of the Ni-II complex of the N3S2 ligand [N3S2Me2](3-) ([N3S2Me2](3-) = deprotonated form of 2-((2-mercapto-2-methylpropyl)(pyridin-2-ylmethyl)amino)-N-(2-mercaptoethyl)acetamide), namely Na[Ni(N3S2Me2)] (2), as a NiSOD model that features sterically robust gem-(CH3)(2) groups on the thiolate alpha-C positioned trans to the carboxamide. The crystal structure of 2, coupled with spectroscopic measurements from H-1 NMR, X-ray absorption, IR, UV-vis, and mass spectrometry (MS), reveal a planar Ni-II (S = 0) ion coordinated by only the N2S2 basal donors of the N3S2 ligand. While the structure and spectroscopic properties of 2 resemble those of NiSODred and other models, the asymmetric S ligands open up new reaction paths upon chemical oxidation. One unusual oxidation product is the planar Ni-II-N3S complex [Ni(L-ox)] (5; L-ox = 2-(5,5-dimethyl-2-(pyridin-2-yl)thiazolidin-3-yl)-N-(2-mercaptoethyl)acetamide), where two-electron oxidation takes place at the substituted thiolate and py-CH2 carbon to generate a thiazolidine heterocycle. Electrochemical measurements of 2 reveal irreversible events wholly consistent with thiolate redox, which were identified by comparison to the ZIP complex Na[Zn(N3S2Me2)] (3). Although no reaction is observed between 2 and azide, reaction of 2 with superoxide produces multiple products on the basis of UV-vis and MS data, one of which is S. Density functional theory (DFT) computations suggest that the HOMO in 2 is pi* with primary contributions from Ni-d pi/S-p pi orbitals. These contributions can be modulated and biased toward Ni when electron-withdrawing groups are placed on the thiolate alpha-C. Analysis of the oxidized five-coordinate species 2(ox)* by DFT reveal a singly occupied spin-up (alpha) MO that is largely thiolate based, which supports the proposed Ni-III-thiolate/Ni-II-thiyl radical intermediates that ultimately yield 5 and other products.
