Megjegyzések:	Novel [2,1-b]naphtho[1,2-e][1,3]thiazin-10-ones were synthesized in 63-89% yield via a three-component reaction of an aromatic aldehyde, [beta]-naphthol, and thiohydantoin in the presence of 10 mol% p-toluene sulfonic acid under solvent-free conditions. This is the first protocol to be reported for the synthesis of the title compounds. The significant features of the present protocol are simplicity, high yields, eco-friendliness, and convenient purification that does not require chromatography.

Megjegyzések:	The reaction of stoichiometric amounts of dialkyl acetylenedicarboxylates with triphenylphosphine in the presence of hydantoins or thiohydantoins afforded stable crystalline phosphorus ylides. These compounds undergo smooth elimination of PPh 3 to produce dialkyl 2-(4,4-diaryl-2,5-dioxoimidazolidin-1-yl)fumarate, 4 or dialkyl 2-(4,4-diaryl-2-mercapto-5-oxo-4,5-dihydro-1H-imidazol-1-yl)fumarate, 7. Single crystal X-ray diffraction study on 4b and 7b proved the structures unambiguously with C=O and SH functionality at the 2-position of the imidazole ring, respectively. Dynamic effects were observed in the NMR spectra of these compounds and were attributed to restricted rotation around the carbon-nitrogen single bonds. Rotational energy barrier (?G#) for their interconversion process of rotational isomersequals to (53.6 and 17.2) ? 2 kcal mol-1.

Cím:	Green regioselective synthesis and theoretical insights into photo- and thermochromic spiro heterocycles: toward optical and thermal sensing applications / Marzieh Jamali, Ali R. Sardarian, Farideh Rezaei, Afshan Mohajeri, Mohammad M.Ghanbari, Gyula Batta

Megjegyzések:	Building on the significant potential of pyrimidine-based molecules for optoelectronic applications, we designed and synthesized a new series of spiro[indoline-pyrido-pyrimidine] derivatives with excellent selectivity. These compounds exhibit novel photochromic and thermochromic properties, addressing the growing need for diagnostic agents with minimal side effects. The regioisomers were identified using 1D, 2D homonuclear and heteronuclear correlation NMR spectroscopy, along with X-ray crystallography. Dynamic 1 H NMR (DNMR) studies revealed that the major isomer (4 sa) is more stable than the minor isomer (4 sb). Optical, electrochemical, and structural analyses of compounds 4aa, 4ab, 4 sa, and 4sb demonstrated the feasibility of chemical reactions converting closed-ring structures to open-ring structures, resulting in notable optical properties due to ring opening. To validate the experimental data, density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations were conducted at the B3LYP/6-31G(d) level, offering insights into the electronic structure and absorption spectra. Additionally, Gibbs free energy (?G) calculations were performed to elucidate the proposed mechanism for open-ring compounds named 5 and 7. This work emphasizes employing the citric acid as a bio-organic catalyst in a green, multi-component domino reaction, underscoring its environmentally sustainable approach. These studies reveal the potential of these compounds for advanced optical and temperature sensing applications, aligning theoretical and experimental approaches to establish a robust foundation for future research.
