Hexacarbonylmolybdenum-induced Reaction of Isoxazoles. Cycloaddition of Isoxazoles with Acetylenic Esters and Related Reactions [PDF]
Abstract In the presence of hexacarbonylmolybdenum, substituted isoxazoles undergo a cycloaddition reaction with dimethyl acetylenedicarboxylate across the C-4–C-5 bond to give 3,4-bis(methoxycarbonyl)pyridine derivatives. In a similar cycloadition of isoxazoles with methyl propiolate, 4-(methoxycarbonyl)pyridine derivatives were also ...

ERNEST COST action overview on the (patho)physiology of GPCRs and orphan GPCRs in the nervous system
G protein‐coupled receptors (GPCRs) are a large family of cell surface receptors that play a critical role in nervous system function by transmitting signals between cells and their environment. They are involved in many, if not all, nervous system processes, and their dysfunction has been linked to various neurological disorders representing important

Simple Access to Isoxazole-Containing Heterocyclic Hybrids: Isoxazole/Oxazole and Isoxazole/Pyridine
Abstract The synthesis of substituted isoxazole–oxazole hybrids by the noncatalytic reaction of methyl 2-diazo-2-(alkyl/aryl/hetarylisoxazol-5-yl)acetates with alkyl and aryl cyanides has been reported. According to DFT calculations, the reaction proceeds through the intermediate formation of a nitrile ylide and its ...

Complexation between oleanolic and maslinic acids with native and modified cyclodextrins [PDF]
Oleanolic (OA) and maslinic (MA) acids are two natural triterpenoids with a wide range of beneficial effects for human health. However, their low solubility and permeability make their application in the food or industry difficult. The complexation of OA

Benzochalcogenodiazoles, Synthesis, and Applications in Medicinal Chemistry and Photomedicine
Benzochalcogenodiazoles (BXD) including benzoxadiazoles, benzothiadiazoles, and benzoselenadiazoles are initially mainly designed for optoelectronic materials as electron‐deficient cores. Nevertheless, they are now extending their application to biology.
