Abstract A diverse series of 3-thioether-functionalized 2,3-dihydrobenzofurans were prepared by an intramolecular radical cyclization/thiolation cascade reaction of alkenyl-tethered arenediazonium salts with thiophenols under transition-metal-free conditions. The mild and practical reaction conditions tolerated various functional groups and afforded the corresponding 2,3-dihydrobenzofurans in moderate

A three-component reaction of 2-(allyloxy)anilines, sulfur dioxide and hydrazines under mild conditions is developed, which gives rise to 1-(2,3-dihydrobenzofuran-3-yl)-methanesulfonohydrazides in good yields. This radical process involves an intramolecular 5-exo-cyclization and insertion of sulfur dioxide.
This invention relates to aryl carbonyl derivatives which are activators of glucokinase which may be useful for the management, treatment, control, or adjunct treatment of diseases, where increasing glucokinase activity is beneficial.

research interest in drug chemistry and organic synthesis in recent years. Herein, we report a facile access to benzocyclic boronates through photopromoted intramolecular arylborylation of allyl aryldiazonium salts. This simple protocol features a broad scope, allowing the formation of variously functionalized borates bearing dihydrobenzofuran, dihydroindene, benzothiophene, and indoline skeletons under
