We report herein a highly exo-selectiveintramolecularDiels–Alderreaction of alkenyl boronates which employs an N–B dative bond-involved bicyclic rigid tether. Complex C(sp3)-rich polycyclic molecules containing up to 8 stereocenters can be readily formed via an operationally simple two-step procedure.

We report a rare polarity-mismatched radical addition reactionusing styrene boronic acids and redox-active N-hydroxyphthalimide (NHPI) esters under photoredox catalysis. The reactiondisplays broad scope with mechanistic investigations supporting a unique synergistic activation pathway that displays chemoselectivity for styrene boronic acids in the presence of other SOMOphiles.
