establishment of valuable functionalized 3-aza-bicyclo[3.1.0]hexane is presented, which allows the formation of multiple chemical bonds in one step under 20 mol % silver(I) catalysts and air conditions. This approach is highly atom economical, easy to perform, and free of external oxidants and features good to excellent yields and gram-scale synthesis. The preliminary study showed that an uncommon silver

meta-Thermocycloadditions of benzene rings was realized for the first time. Distinct to the meta-photocycloadditions, this reaction was proposed to proceed via [4π+2π] cycloadditions of Wheland intermediates from the electrophilic dearomatization of benzene rings. A broad spectrum of readily available C(sp2)-rich aniline-tethered enynes were transformed into C(sp3)-rich 3D complex polycyclic architectures
