Given the importance of quinazolinones and carbonylative transformations, a palladium‐catalyzed four‐component carbonylativecoupling system for the synthesis of diverse 4(3H)‐quinazolinone in a concise and convergent fashion has been developed. Starting from 2‐bromoanilines (1 mmol), trimethyl orthoformate (2 mmol), and amines (1.1 mmol), under 10 bar of CO, the desired products were isolated in good

The glycosyl 1,2,3-triazoles are expediently accessible from readily available sugar-derived glycosyl azide by utilizing modular CuAAC “ClickChemistry”, and the resulting glycohybrid skeleton possesses efficient metal-coordinating centers that support a wide range of metal-mediated efficient catalysis in various imperative organic transformations. Here, we designed and developed pyridyl glycosyl triazoles
