The present application provides bifunctional compounds which act as protein degradation inducing moieties. The present application also relates to methods for the targeted degradation of endogenous proteins through the use of the bifunctional compounds that link a cereblon-binding moiety to a ligand that is capable of binding to the targeted protein which can be utilized in the treatment of proliferative disorders. The present application also provides methods for making compounds of the application and intermediates thereof.
Electrophilicity of α-oxo gold carbene intermediates: halogen abstractions from halogenated solvents leading to the formation of chloro/bromomethyl ketones
α-Oxo gold carbenes generated via intermolecular oxidation of terminal alkynes are shown to be highly electrophilic and can effectively abstract halogen from halogenated solvents such as 1,2-dichloroethane or 1,2-dibromoethane. Chloro/bromomethyl ketones are prepared in moderate efficiencies in one step using Ph3PAuNTf2 as the catalyst and 8-methylquinoline N-oxide as the oxidant.

2‐aryl‐ and 2‐alkyl‐1H‐indoles. Readily or commercially available α‐chloromethyl‐aryl or ‐alkyl ketones are used as the precursors. Indoles containing substituents, including halogens, at the benzene ring are also easily accessible simply by use of the appropriate substituted aromatic amine.
One-Step Synthesis of Methanesulfonyloxymethyl Ketones<i>via</i>Gold-Catalyzed Oxidation of Terminal Alkynes: A Combination of Ligand and Counter Anion Enables High Efficiency and a One-Pot Synthesis of 2,4-Disubstituted Thiazoles
Mor‐DalPhos as the P,N‐bidentate ligand and mesylate as the counter ion, the resulting gold(I) complex catalyzes efficient oxidative transformations of various terminalalkynes into synthetically versatile methanesulfonyloxymethyl ketones. The mild reaction conditions and highefficiency permit the one‐pot synthesis of a range of valuable 2,4‐disubstituted thiazoles by subjecting the resulting reaction
