The hydration of haloalkynes to give α-halomethyl ketones was achieved based on a combination of a Cu(OAc)2 catalyst and a TFA (trifluoroacetic acid) promoter. This is the first synthesis of chloro/bromo/iodo methyl ketones through a hydration reaction catalyzed by a recyclable catalytic system. The catalytic system has a wide substrate scope and excellent chemoselectivity, and the procedure can also

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.

An efficient method for generation of alpha-lambda3-iodanyl ketones from (Z)-(2-acetoxyvinyl)(phenyl)-lambda3-iodanes was developed. The method involves ester exchange of (Z)-2-acetoxyvinyl-lambda3-iodanes with methanol in the presence of triethylamine. alpha-lambda3-Iodanyl ketones react with a variety of nucleophiles such as halides, thiols, phosphines, phosphinic acids, and phosphates, under the
