The particular nature of boron compounds allows an ample modularity of their properties ranging from Lewis acids, C‐nucleophiles, B‐nucleophiles, or even conjunctive reagents for new synthetic manipulations. Moreover, the increasing demand for functionalized boron derivatives for pharmaceutical or material science applications requires the development of new synthetic methods for boron introduction in organic compounds. This review summarizes the possible combinations of boron derivatives with a variety of strained heterocycles reported in the most recent literature.
