Anthore-Dalion, Lucile; Zard, Samir Z. (2017): Chemoselective Reduction: Xanthates as Traceless Precursors of Polyfunctionalized alpha,alpha-Dichloroketones. In: Organic Letters, Vol. 19, No. 20: pp. 5545-5548

The use of BEt3 center dot H2O has allowed the chemoselective reductive dexanthylation in the presence of the very fragile alpha,alpha-dichloroketone motif. This has solved a major hurdle in our approach to this important, but hitherto grossly understudied, family of compounds and opened access to a number of very useful synthetic transformations.
