Eugenol‐derived organic liquids as an in situ CO2 capturing and conversion system for Eugenol‐based polycarbonate synthesis

The significant development of catalytic biomass conversion has provided a large library of chemicals ready for subsequent upgrading to polymerisable monomers for the design and preparation of sustainable polymers. In this study, hydroxyethylation of eugenol by using green ethylene carbonate as alkylation reagent and cheap tetrabutylammonium iodide...

Recent Advances in the Chemistry of Heavier Group 14 Analogues of Carbonyls

Heavier group 14 analogues of carbonyls (R2E=O, E=Si, Ge, Sn, Pb) with high polar E=O double bonds have attracted much attention in recent years. In this review, we summarized the recent advances in the chemistry of heavier analogues of carbonyls, mainly focusing on their synthesis, structure and reactivity. Abstract Heavier analogues of carbonyls,...

Base‐free Air Oxidation of Chitin‐derived Glucosamine to Glucosaminic Acid by Zinc Oxide‐supported Gold Nanoparticles

Highly-valued glucosaminic acid was produced by the oxidation of chitin derived glucosamine under ambient air and base-free conditions. Abstract In this study, glucosaminic acid (GlcNA) was produced with the highest yield of ∼85% from chitin biomass-derived glucosamine (GlcN) at 35 °C under atmospheric air in water, by using zinc oxide-supported...

Highly Active Cyclic Zinc(II) Thione Catalyst for C−C and C−N Bond Formation Reactions

First discrete mononuclear zinc(II) thione catalyzed Knoevenagel condensation reactions, and 2,3-dihydroperimidine synthesis are reported with the best catalytic activities. Abstract The first discrete seven-membered cyclic zinc(II) complex catalyzed room temperature Knoevenagel condensation reactions, and the synthesis of perimidine derivatives...

Coumarin as a Surrogate for Protection‐group‐free Synthesis of o‐Hydroxy Stilbenes: Hydrolysis‐Decarboxylation‐Heck Coupling Reactions in One pot

2-Hydroxystyrylbenzene scaffold is found in various compounds that are widely applicable in medicinal chemistry as well as material chemistry. Here, a successful attempt is made to develop a one-pot protocol for the synthesis of 2-hydroxystilbene derivatives via hydrolysis of natural coumarins followed by in situ decarboxylative Heck coupling with haloarenes....

Toughened Hydrogels for 3D Printing of Soft Auxetic Structures

Materials with negative Poisson's ratio have attracted considerable attention and offered high potential applications as biomedical devices due to their ability to expand in every direction when stretched. Although negative Poisson's ratio has been obtained in various base materials such as metals and polymers, there are very limited works on hydrogels...

Silver Catalyzed One‐Pot Three‐Component Synthesis of α‐Aminonitriles and Biologically Relevant α‐Amino‐phosphonates

A simple silver salt (AgSbF6) catalyzed aminophosphonylation and Strecker reaction have been developed and successfully applied to a wide range of substrates (>55 substrates). This solvent-, ligand-, and base-free one-pot three component protocol operates effectively at room temperature to provide diversified α-aminophosphonates and α-aminonitriles,...

Mechanofluorochromism of 2‐Biarylyl Cinchoninic Acids with High Sensitivity and Large Mechanochromic Shift

A series of MFC materials with a 2-biarylyl cinchoninic acid skeleton have been synthesized, which are based on interconversion of classical/ frustrated Brønsted pairs. These materials have mechanochromic shift of up to 115 nm, as well as highly contrast, highly sensitivity and highly responsiveness properties. Abstract In recent years, organic...

3D Printing of Skin Equivalents with Hair Follicle Structures and Epidermal‐Papillary‐Dermal Layers Using Gelatin/Hyaluronic Acid Hydrogels

A gelatin and hyaluronic acid-based bioink was fabricated and triple-layered skin tissue analogs were 3D printed. Compared to conventional 3D printed skin tissues, this study proposes novelties which are the presence of a papillary layer and hair follicle unit development. The papillary layer supports dermis-epidermis interaction and induces spontaneous...

Recent Advances in the Practical Synthesis of C1 Deuterated Aromatic Aldehydes Enabled by Catalysis and Beyond

Selective deuteration of aromatic aldehydes has a wide application in isotopic labeling. Deuterated aldehyde is a useful precursor in synthetic organic intermediates, mechanistic studies, designing isotope-labeled drug molecules and pharmaceutical chemistry. There are diverse methodologies have developed to access aldehyde-d by various practical and...
