The proteolysis-targeting chimeras (PROTACs) have become an integral part of different
stages of drug discovery. This growing field, therefore, benefits from advancements
in all segments of the design of these compounds. Herein, an efficient and optimized
synthetic protocol to various von Hippel-Lindau (VHL) ligands is presented, which
enables easy access to multigram quantities of these essential PROTAC building blocks.
Moreover, the elaborated synthesis represents a straightforward approach to further
explore the chemical space of VHL ligands.
