Most of the reported reactions occur in syn addition mode. Accordingly, anti-selective boron addition to alkynes is an important challenge in modern organic synthesis. This chapter describes successful examples of anti-selective boron additions. T2 - Advances in Organoboron Chemistry towards Organic Synthesis ER -
