In this letter, an efficient one-pot asymmetric sequential reaction is achieved by organo/transition metal relay catalysis in constructing two consecutive C-C bonds, which involves enantioselective amino squaramide catalytic Mannich-type addition of pyrazolones to isatin-derived ketimines and a subsequent palladium catalyzed diastereoselective allylic alkylation of pyrazolones with allylic acetates. An array of novel pyrazolone-aminooxindole-propylene structural motifs are obtained in a high level of yield and with excellent enantio- and diastereoselectivity (up to 95% yield, >20:1 dr, >99% ee). This methodology features the formation of vicinal quarternary carbon-stereocenters, and the second all-carbon tetrasubstituted stereogenic center is induced by joint action of the achiral palladium catalysis and the chiral environment generated from the Mannich step. Moreover, the usefulness of this methodology is highlighted by converting the allylic product into the carbonyl compound.

Strategies for altering the reaction pathway of reactive intermediates are of significant importance in diversifying organic synthesis. Enol silyl ethers, versatile enolate equivalents, are known to undergo one-electron oxidation to generate the radical cations that spontaneously form electrophilic alpha-carbonyl radicals via elimination of the silyl groups. Here, we demonstrate that close scrutiny of the property of the radical cations as strong C-H acids enables the identification of a catalyst system consisting of an iridium-based photosensitizer and 2,4,6-collidine for the generation of nucleophilic allylic radicals from enol silyl ethers through one-electron oxidation-deprotonation sequence under light irradiation without the desilylation of the radical cation intermediates. The resultant allylic radicals engage in the addition to electron-deficient olefins, establishing the selective allylic C-H alkylation of enol silyl ethers. This strategy is broadly applicable, and the alkylated enol silyl ethers can be transformed into highly functionalized carbonyl compounds by exploiting their common polar reactivity.

The current work investigates the performance of a real-time scan conversion algorithm for generating a 2-D ultrasound image from a laterally scanned single-element ultrasound transducer, which has applications in point-of-care devices such as for skin imaging. The algorithm employs a fixed calibration curve to update a predefined image grid in real time. Simulations showed that the calibration curve (with a maximum of 1) is robust to changes in scatterer concentration (8.3 x 10(-3) mean absolute error), signal to noise ratio (1.0 x 10(-3) mean absolute error for -5 dB SNR), and can be accurately predicted from a small number (31) of point scatterers (6.9 x 10(-3) mean absolute error). Good agreement was also found between the calibration curves obtained from simulated and experimental data (1.19 x 10(-2) mean absolute error). The scan conversion algorithm was validated by evaluation of the position estimation errors on both simulations and experiments. Clinical images of skin lesions (N = 20) demonstrate the feasibility of the algorithm for real, non-homogeneous tissue. Use of a fixed calibration curve compared to an adaptive calibration curve gave similar accuracies in the scanning step size range of 150-350 mu m (with an average overlap of the accuracy ranges of 92.94% for simulations and 42.83% for experiments), and a 350-fold improvement in computation time.

A sequential and general strategy has been successfully developed for the synthesis of spiropyrazolone scaffolds. This intriguing transformation of the asymmetric multicomponent catalysis process was realized with the combination of Michael addition/chlorination/nucleophilic substitution in a one-pot sequence, giving rise to a series of spiropyrazolones with fully substituted cyclopropanes and spiro-dihydrobenzofurans containing continuous stereogenic centers in good yields with excellent stereoselectivities.

The (solid + liquid) equilibrium for Terephthaldialdehyde, 4-Nitro-o-phennylenediamine, 2,4-dihydro- 5-methyl-2(4-methylphenyl)-3H-pyrazol-3-one (also named 1-(p-toly1)-3-methyl-5pyrazolone (PTMP)), 2-Amino-5-methylthiazole and 5-chloro-1-methyl-4-nitroimidazole in 18 solvents is correlated with semi-empirical models at temperatures T = 273.15 – 318.15 K under a pressure of 101.2 kPa. Moreover, a modified Apelblat model, lambda h model, Wilson model, NRTL model, new flexible equation as Akbari, Dideban and Farhang model (ADF) and for first time the modified Scatchard-Hildebrand equation were utilized to calculate the experiment values. The performance of both ADF and modified Scatchard-Hildebrand equation have been checked by calculating the solubility data with the AARD% of 1.3808% (for 775 data points) and 0.65% (for 100 data points), respectively. The Wilson model is applied to estimate the mixing Gibbs energy, mixing enthalpy, mixing entropy, activity coefficient (ln gamma(infinity)(1)) and reduced excess enthalpy (H-I(E,infinity)) at infinitesimal concentration were calculated.

New tri- and tetraalkyl-substituted o-benzoquinones were synthesized based on 5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalene-2,3-diol derivatives. The new compounds were characterized by spectroscopic and electrochemical methods. The reactivity of o-benzoquinones was evaluated in the photoreduction and initiation of photopolymerization of oligocarbonate dimethacrylate (OCM-2) in the presence of N,N-dimethylcyclohexylamine and in the inhibition of MMA polymerization. The introduction of the methyl substituent into the benzene ring has a weak effect on the inhibitory activity of o-benzoquinone, whereas the (3,5-dimethylpyrazol-1-yl)methyl substituent enhances the inhibitory effect of 4,5-di-tert-alkyl-substituted o-benzoquinone.
