Abstract
An efficient B(C6F5)3 catalyzed protocol for the synthesis of oxindole fused 1,3-oxazepanes from pyrrolidine-substituted aryl alkynones has been developed. A ring expansion of pyrrolidine and dual hydride transfer were involved in the cascade reactions. Transition metal-free conditions, good functional group tolerance and operational simplicity make this C(sp3)-H functionalization methodology attractive.
