silver‐promoted azido‐carbocyclization of activatedalkenesvia a radical pathway has been developed. Azido oxindoles, which hold great potential for subsequent transformation of the azido unit, are efficiently constructed by this protocol. Radical addition and CH functionalization processes are involved in this transformation with the formation of CN and CC bonds. Silver is observed to promote the

A silver-prompted carbonitration of alkenes involving concomitant direct C-H functionalization and C-N bond formation to synthesize nitrating oxindoles has been developed. The CR TH2 receptor antagonist skeleton can be obtained from one of the products with further modification.
