We report herein a straightforward access to α-[(diethoxyphosphoryl)difluoromethyl]thiolated ketones. The methodology, which involves the nucleophilic [Cu]CF2PO(OEt)2 species, has allowed the formation of the targeted compounds in moderate to high y

Herein, we report a copper salt-controlled divergent reactivity toward α-diazocarbonyl compounds. By a simple change of the copper counteranion under identical reaction conditions, the reported method allowed an easy access to either (Z)-α-fluorovi

International audience; The difluoromethyl phosphonate motif plays a crucial role in the development of bioactive molecules as it is considered as a phosphate bioisoster. Since 2010,a renewal of interest to enlarge the panel of reactions to access th
Fully functionalized medium-sized cyclic ethers, of the type found in fused polyether natural products, have been prepared by sequential ring-closing diene metathesis, conversion of the resulting cyclic enone into an allylic enol carbonate, and Tsuji

A study of the preparation and of the reactivity of N-tert-butanesulfinyl glycosylamines is reported for the first time. As they react readily as latent imine equivalents with a variety of carbon nucleophiles, these new carbohydrate derivatives const

Difluoromethylated arenes are scaffolds of great interest. We report herein a mild and general method for the introduction of the CF2PO(OEt)2 moiety into arenes. The CuCF2PO(OEt)2 species, which is generated in situ from the corresponding silylated d

We report the direct introduction of the CF2CO2Et moiety into electron-rich arenes. The copper-catalyzed process uses commercially available and inexpensive BrCF2CO2Et as a fluorinated building block. This radical-free reaction proceeds smoothly to g

(+)-Hyacinthacines A 1 and A 2 have been prepared from an easily available, advanced intermediate. The non-chiral pool approach features a dichloroketene–enol ether [2+2] cycloaddition and a dihydroxylation or epoxidation as key stereoselective tra

International audience; Herein, a general procedure to access CF2PO(OEt)2‐containing molecules is reported. The reagent CuCF2PO(OEt)2 is accessible by a simple protocol and a broad range of substrates can be functionalised. The procedure allows the
