59937-01-8. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 59937-01-8, Name is Ethyl 2-phenylthiazole-4-carboxylate. In a document type is Article, introducing its new discovery.

The efficient synthesis of 2-substituted thiazoles and benzothiazoles has been accomplished employing readily available cysteine esters and 2-aminobenzenethiols as N and S sources. The reaction proceeds under an I2/TBHP system and involves a one-pot tandem cyclization and oxidation sequence. A diverse range of aldehydes is amenable for this transition-metal-free protocol, which provides an alternative method to rapidly access thiazole-containing molecules.

4-Carbethoxymethyl-2-[(chloroacetyl/alpha-chloropropionyl/alpha- bromobutyryl/alpha-chloro-(alpha-phenylacetyl)amino]thiazoles (I-IV) were synthesized by reacting 4-carbethoxymethyl-2-aminothiazole with chloroacetyl chloride, alpha-chloropropionyl chloride, alpha-bromobutyryl bromide and alpha-chloro- alpha-phenylacetyl chloride, respectively. Furthermore, I-IV were refluxed with ammonium thiocyanate to give 2-[(4-carbethoxymethylthiazol-2-yl)imino]-4- thiazolidinones (V-VIII). V was refluxed with various aromatic aldehydes to give 5-arylidene-2-[(4-carbethoxymethylthiazol-2-yl)imino]-4-thiazolidinones (IX-XIV). The structures of synthesized compounds were confirmed by elemental analyses, hydrolysis, UV, IR, 1H-NMR and EI mass spectral data. The antimicrobial activities of the compounds were assessed by microbroth dilution technique using Mueller-Hinton broth and Mueller-Hinton Agar. In this study, Staphylococcus aureus ATCC 6538, Staphylococcus epidermidis ATCC 12228, Escherichia coli ATCC 8739, Klebsiella pneumoniae ATCC 4352, Pseudomonas aeruginosa ATCC 1539, Salmonella typhi, Shigella flexneri, Proteus mirabilis and Candida albicans ATCC 10231 were used as test microorganisms. Among the tested compounds, XI and XIV showed activity against S. aureus (MIC: 78 mug/ml, 1.6 mug/ml), whereas compound V had an activity against S. flexneri (MIC: 39 mug/ml) and compound I against C. albicans (MIC: 125 (mug/ml). Compounds I, IV-XIV were also evaluated for antituberculosis activity against Mycobacterium tuberculosis H37Rv using the BACTEC 460 radiometric system and BACTEC 12B medium. Only compounds I and XIV showed 86% and 67% inhibition in the primary screen.

Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn¡¯t involve a screen. 18640-74-9, C7H11NS. A document type is Conference Paper, introducing its new discovery., 18640-74-9

An empirical model was developed to describe and predict the change in gas-liquid partition behaviour of a wide range of volatile compounds in aqueous sucrose solutions. The static equilibrium headspace concentrations of 40 volatiles (from different chemical classes e.g. pyrazines, alcohols, esters and ketones and with different physical properties e.g. volatility and solubility), were measured above aqueous sucrose solutions [0-65% (w/v)]. As sugar concentration increased, the headspace concentration of some compounds increased, whilst others stayed the same or decreased. The changes in volatile headspace concentrations were correlated (using partial least squares regression) with a range of physicochemical descriptors which were calculated from the compound structure. The model was composed of seven physicochemical descriptors and had a regression coefficient, R2=0.74. An external test set was used to validate the model. The key descriptors in the model were (log P)2, LUMO energy and a connectivity index term. Copyright (C) 2000 Elsevier Science Ltd.

The difunctional substrate 2,4-dibromothiazole 2 was transformed into the title compounds 1 by consecutive Pd(0)-catalyzed cross-coupling reactions. Aryl zinc reagents which were prepared by ortho-lithiation of compounds 3 and subsequent transmetalation were used as carbon nucleophiles in the first coupling reaction. By this means, an aryl substituent was attached to the 2-position (50-62% yield). A succeeding cross-coupling with arylboronic acids 4 occurred at the 4-position of the intermediate 4- bromothiazoles 5 (76-97% yield). (C) 2000 Elsevier Science Ltd.

The oxoketene dithioacetals 1 undergo regioselective 1,2-addition with 2-lithiomethyl-4-methylthiazole (2a) and 2-lithiomethylthiazoline (3) to afford the carbinol acetals 4 which on borontrifluoride etherate assisted cyclization yield the corresponding substituted and annelated 3-methyl-5-methylthiothiazolo[3,2-a.] pyridinium tetrafluoroborates (5a-S, 8a, b, 10, 12) and the dihydro derivatives (23-25) respectively in good yields. The corresponding 2-methyl-5-phenylthiazole (16) however underwent both nuclear and side chain deprotonation and yielded a mixture of products under similar reaction conditions.
