An enantioselective Mannich reaction between 3-fluorooxindoles and pyrazolinone ketimines has been developed for the construction of amino-pyrazolone-oxindoles containing stereogenic C-F units. Based on this new protocol that allows for the generation of two adjacent tetrasubstituted stereocenters, a variety of structurally diverse fluorinated amino-pyrazolone-oxindoles were obtained in good to excellent yields with excellent diastereoselectivities and enantioselectivities (up to 98% yield, >20 : 1 dr and >99% ee). What’s more, good yield and high stereoselectivities were obtained in the gram-scale reaction.

A highly efficient iridium-catalyzed cascade annulation of pyrazolones and sulfoxonium ylides to access various pyrazolo[1,2-alpha]cinnoline derivatives has been achieved. This novel approach expanded the application scope of coupling partners to ylides. The control experiments were performed to give insight into the mechanism of this reaction.

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.

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.

A new semi-theoretical equation is suggested for correlation of solid-liquid solubility data with temperature. 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.
