Dichloroacetophenone is a pyruvate dehydrogenase kinase 1 (PDK1) inhibitor with suboptimal kinase selectivity. Herein, we report the synthesis and biological evaluation of a series of novel dichloroacetophenones. Structure-activity relationship analyses (SARs) enabled us to identify three potent compounds, namely 54, 55, and 64, which inhibited PDK1 function, activated pyruvate dehydrogenase complex

An efficient and facile method is reported for the synthesis of a series of α,α-dichloroketones. The direct dichlorination of methyl ketones and 1,3-dicarbonyls using an excess amount of sulfuryl chloride affords the corresponding -dichloro compounds in moderate to excellent yields. Moreover, the protocol features high yields, broad substrate scope, and simple reaction conditions without using any
Halogenation Using Quaternary Ammonium Polyhalides. XXXII. Dichlorination of Aromatic Acetyl Derivatives with Benzyltrimethylammonium Tetrachloroiodate
The reaction of aromatic acetyl derivatives with 2 molar amounts of benzyltrimethylammonium tetrachloroiodate in acetic acid at 70 °C for several hours gave dichloroacetyl derivatives in good yields.

Electrochemical Oxidative Oxydihalogenation of Alkynes for the Synthesis of α,α-Dihaloketones
An electrochemical oxydihalogenation of alkynes has been developed for the first time. Using this sustainable protocol, a variety of α,α-dihaloketones can be prepared with readily available CHCl3, CH2Cl2, ClCH2CH2Cl, and CH2Br2 as the halogen source under electrochemical conditions at room temperature.
