General Description

3-Phenylumbelliferone is a chemical compound used extensively in cellulose research due to its fluorescent properties, making it easier to monitor the processes involved in cellular activities. Its molecular formula is C16H12O3 and it is characterized by pale yellow crystalline properties. It has other variations such as coumarin and is also known for its sweet-smelling hawthorn-like scent. Toxicity studies indicate that high concentrations of 3-Phenylumbelliferone may pose certain hazards, however, its toxicity level is generally considered low. More scientific research is necessary to further understand its full chemical properties and potential applications.

Dual Role of Oxoaldehydes: Divergent Synthesis of 3-Aryl- and 3-Aroylcoumarins

A facile and efficient synthetic approach to various valuable 3-aryl- and 3-aroylcoumarins by the direct arylation and aroylation of coumarins with glyoxals in a metal-free manner is presented. The aryl glyoxal is for the first time recognized to serve as an aryl surrogate in addition to its role as an aroyl transfer reagent via a simple switch in reaction conditions. The approach accommodates a broad substrate scope and high yields of the two types of cross-coupling reactions starting from identical starting materials.

Chlorophyll-catalyzed photochemical regioselective coumarin C-H arylation with diazonium salts

This communication describes the development of a mild method for the cross-coupling of the C3-position of coumarin with an array of diazonium salts mediated by chlorophyll as a biocatalyst via visible light catalysis. A natural pigment such as chlorophyll is used as a green photosensitizer and environmentally benign catalyst. This general and easy procedure provides a transition-metal-free alternative for the formation of 3-aryl coumarin derivatives at room temperature with good to excellent yields. This journal is

3-Aryl Coumarin Derivatives Bearing Aminoalkoxy Moiety as Multi-Target-Directed Ligands against Alzheimer's Disease

Two series of novel coumarin derivatives, substituted at 3 and 7 positions with aminoalkoxy groups, are synthesized, characterized, and screened. The effect of amine substituents and the length of cross-linker are investigated in acetyl- and butyrylcholin
