Memory of Chirality in Radical Addition–Translocation–Cyclization Cascades
Helvetica Chimica Acta, EarlyView.Radical addition–translocation–cyclization cascades of chiral alkynes show striking memory of chirality (MoC), with strong retention of configuration when fast, polarity favored cyclization are involved. The most effective system employs a highly electron‐poor pentafluorobenzenesulfonyl group.
