Abstract

Alkenyl‐substituted dihydroaromatic boronic esters, generated by neutral cobalt(I)‐catalysed Diels–Alder reactions, reacted under palladium catalysis conditions with diiodobenzene, bromoiodobenzene and iodoaniline derivatives for the synthesis of regioselectively substituted phenanthrene and phenanthridine derivatives.
