A series of cocrystals and a salt of the indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) (plant hormone) with 2-aminopyrimidine (2AP), 2-amino-4,6-dimethylpyrimidine (2A-4,6-DMP) and 2,4,6-triaminopyrimidine (2,4,6-TAP) were successfully prepared, with an aim to explore the robustness of acid-aminopyrimidine synthon and its behaviour, with a change in the environment at 4,6 position of the pyrimidine ring. The formation of cocrystals/salt are examined on their Delta pKa values and were characterized by powder X-ray diffraction (PXRD), fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC) and their structures determined by single crystal X-ray diffraction (SCXRD). Additionally, Hirshfeld surface analysis was done to investigate the strength of the interactions and the overall percentage of short contacts and their impact on the overall packing.

The synthesis of substituted indoles has received great attention in the field of organic synthesis methodology. C-H activation makes it possible to obtain a variety of designed indole derivatives in mild conditions. Ruthenium catalyst, as one of the most significant transition-metal catalysts, has been contributing in the synthesis of indole scaffolds through C-H activation and C-H activation on indoles. Herein, we attempt to present an overview about the construction strategies of indole scaffold and site-specific modifications for indole scaffold via ruthenium-catalyzed C-H activations in recent years.

In this work, a novel ECL immunosensor based on self-enhanced luminophore and ultrathin 2D nickel MOF nanosheets was fabricated for sensitive and specific detection of h-FABP. Initially, the porous ultrathin Ni-TCPP (Fe) nanosheets with high specific surface area and plentiful active sites were newly synthesized, which could enhance ECL signal of luminol by the superior peroxidase mimics activity towards H2O2 decomposition. Then, PEI and luminol were simultaneously immobilized on Ni-TCPP (Fe) nanosheets to construct self-enhanced solid state luminophore (Ni-TCPP (Fe)-PEI-Lum), possessing desirable stability and high ECL efficiency. Furthermore, poly (indole-5-carboxylic acid) (PICA) worked as substrate with outstanding conductivity and abundant binding sites to improve sensitivity. Under optimal conditions, the designed ECL immunosensor exhibited a wide dynamic range from 100 fg mL(-1) to 100 ng mL(-1) and a low detection limit of 44.5 fg mL(-1). In addition, the ECL immunosensor behaved excellent specificity and was successfully applied to detect target h-FABP protein in complex physiological matrix. Therefore, this work may provide an alternative method for biomarker detection in clinical diagnosis and expand the application potential of 2D MOF nanosheets in ECL technique.

A conformationally rigid chiral bicyclic skeleton tethered bipyridine-Zn(OTf)(2) complex facilitated the enantioselective Friedel-Crafts alkylation of indoles with trans-beta-nitroarylalkenes in an enantioselective manner at elevated temperature. Indoles reacted smoothly with beta-nitroarylalkenes to generate the corresponding 3-(2-nitroalkyl) indoles in good to excellent yields (up to 94%) with moderate to excellent enantioselectivities (up to 91%). The stereochemical outcome of the product from indole and trans-beta-nitrostyrene in the presence of the CRCB tethered bipyridine-Zn(OTf)(2) complex and the DFT calculation of the CRCB tethered bipyridine-Zn: trans-beta-nitrostyrene complex support the si-face attack of indole on trans-beta-nitrostyrene.
