The selective hydrogenation of quinolines to 1,2,3,4-tetrahydroquinolines(py-THQ) and its derivatives has attracted a considerable amount of attention as they show great versatility in many pharmaceuticals, agrochemicals, and fine chemicals. Over the past few decades, great breakthroughs have been achieved in the controlled synthesis of efficient heterogeneous catalysts used for the selective hydrogenation of functionalized quinoline compounds, which allow one to correlate the structure-property relationships. In this review, we will summarize the recent significant progress achieved in this field covering the synthetic strategies, microstructural and chemical features, catalytic performance, and internal relationships. State-of-the-art noble metal-based single(Pd, Pt, Ru, Rh, Ir and Au) and bi/multi-metallic catalysts(RuCu, AuPd, and PdNi) are first introduced, followed by a summary of earth-abundant metal-based catalysts(Co, Fe, Ni, and Cu). Finally, the dehydrogenation of N-heterocycles is introduced to form a reversible hydrogenation/dehydrogenation system for H2 storage, which can be employed in a liquid organic hydrogen system. Furthermore, the reaction mechanism and future research direction in these areas are also discussed. This review will deepen our understanding of the catalytic transformation of N-heterocycles and provide guidance for researchers on the rational design of catalysts.

Nowadays, the treatment efficacy of the chemotherapeutic drugs are far from satisfying on account of poor tumor specificity and serious side effects. Therefore, drug delivery system(DDS) has attracted great attention because of the considerable augmentation of the treatment efficacy and the significant reduction of the side effect. Generally, the facile synthesis, long-term stability, biocompatibility, high loading efficiency, and targeted delivery to cancer cells are important for the practical application of DDS. Furthermore, it is critical to release the drug triggered by stimuli associated with the specific microenvironmental changes with sustained manner. Heretofore, most of the DDS are polymer-based. However, the complex synthesis, the involvement of the toxic agents associated with the synthesis, the complicated degradation products, and thus the potential side effects greatly limit their application. Owing to the significant advantages over synthetic polymers, e.g. simple preparation and reduced involvement of toxic agents, recently, inorganic materials were considered as promising DDS candidates, e.g. mesoporous silica. Compared with silica, Ca CO own the good biocompatibility and biodegradability, and thus might be an ideal DDS ***, bimodal porous Ca CO/folate(FA) hybrid hollow spheres(Ca CO/FA HSs) were prepared through a facile green method without involving any toxic agents under ambient conditions. Through time-dependent SEM observations, the formation mechanism of the HSs was proposed as Ostwald ripening. Because of the special morphological features of the typical product, e.g. the presence of hollow cavity and bimodal pores,Ca CO/FA HSs could efficiently load the anticancer drug doxorubicin(DOX) and release it with sustained manner. Furthermore, because of the p H sensitivity, good biocompatibility and biodegradability of CaCO,CaCO/FA HSs could release DOX in controlled and sustained manner triggered by the weak acidic microenvironment

Amides are one of the most ubiquitous and important functional groups in natural products and synthetic drugs. The research of forming methods for amide is of great significance. And also it is now a hotspot in the research of the synthetic method. Hypervalent iodine reagents due to its ready availability, low toxicity, easy handling, and reactivity similar to that of heavy metal reagents were used to the N-N, S-N or C-C bond formation, and provide a new strategy for organic ***, we describe a new method to synthesize varieties of functionalized amides in the presence of PIFA in moderate to good yields starting from hydrazides and nitriles.
