A radical Smiles rearrangement strategy for allowing an unprecedented [3 + 2]/[3 2] carboannulation of dienynes with arylsulfonyl chlorides using cheap copper catalysis is described.

Over the decades the Smiles rearrangement and its variants have become essential synthetic tools in modern synthetic organic chemistry. In this mini-review we summarized some very recent results of the radical version of these rearrangements. The selected examples illustrate the synthetic power of this approach, especially if it is incorporated into a domino process, for the preparation of poly...

Rearrangement reactions are a very powerful tool for the conversion of simple substrates into highly functionalized products in organic chemistry. In combination with an attractive initiation process, such as visible-light catalysis, these particularly powerful.
