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.

  • 13 The X-ray crystallographic data collection for compounds 14 was performed on a Bruker X8-Kappa ApexII diffractometer at 100(2) K. The diffractometer was equipped with a low-temperature device (Kryoflex I, Bruker AXS) and used Mo-K α radiation (λ = 0.71073 Å). Intensities were measured by fine-slicing ϕ- and ω-scans and corrected for background, polarization, and Lorentz effects. Semiempirical absorption corrections were applied for all data sets by using Bruker’s SADABS program. The structures were solved by direct methods and refined anisotropically by the least-squares procedure implemented in the ShelX-2014/7 program system. Hydrogen atoms were included isotopically using the riding model on the bound carbon atoms. CCDC 1986177 contains the supplementary crystallographic data for this paper.
