radical reaction of N-sulfonyl-2-allylanilines with [60]fullerene has been developed to efficiently provide novel and scarce (2-indolinyl)methylated hydrofullerenes, featuring a broad substrate scope and excellent functional group tolerance. A plausible reactionmechanism for the formation of (2-indolinyl)methylated hydrofullerenes is proposed on the basis of the experimental results. In addition, further
Syntheses of hitherto unreported azepine- and azocine-annulated heterocycles have been developed in excellent yields via a catalyzed aromatic aza-Claisen rearrangement followed by ring-closing metathesis using Grubbs first-generation catalyst.
