In an article, author is Alsharif, Meshari A., once mentioned the application of 2873-29-2, Application In Synthesis of (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate, Name is (2R,3S,4R)-2-(Acetoxymethyl)-3,4-dihydro-2H-pyran-3,4-diyl diacetate, molecular formula is C12H16O7, molecular weight is 272.25, MDL number is MFCD00063253, category is piperidines. Now introduce a scientific discovery about this category.
One pot synthesis, physicochemical and photophysical investigation of biologically active pyridine-3-carboxylate (ECPC) as probe to determine CMC of surfactants in organized media
Ethyl 4 – (9-ethyl-9H-carbazol-3-yl) – 2 – methyl – 5- oxo – 4, 5 – dihydro-1H-indeno[1,2-b]pyridine-3-carboxylate (ECPC) was prepared by one pot multi component reaction of 9-ethyl-9H-carbazole-3-carbaldehyde, indane-1,3-dione, ethyl acetoacetate and ammonium acetate in the presence few drops of piperidine. Structure of the title compound (ECPC) was confirmed by the spectroscopic techniques (FT-IR, H-1-NMR, C-13-NMR, EI-MS) and elemental analysis. Photophysical parameter of the ECPC such as transition dipole moment, extinction coefficient, stokes shift, oscillator strength, fluorescence quantum yield were calculated by using the different solvents (based on the polarity). The results of compound ECPC showed red shift in absorbance and emission spectrum with increase in the polarity of the solvents from n-heptane to DMSO. Emission spectrum of ECPC effected with anionic and cationic surfactant so ECPC can be used as probe to determine critical micelle concentrations (CMC) of anionic sodium dodecyl sulfate (SDS) and cationic cetyltrimethylammonium bromide (CTAB) surfactant. The in-vitro antibacterial activity of ECPC was examined by the disk diffusion and minimum inhibitory concentration (MIC) methods against two Gram-positive and two Gram-negative bacteria by using Tetracycline as reference drug.
