We report a straightforward method for the synthesis of five-membered 1,3-dioxolan-4-ones by an unprecedented oxidative alkene geminal difunctionalization strategy using α-hydroxy carboxylic acids. Under the geminal oxidative addition conditions, va

Thioureas have emerged as effective hydrogen-bonding catalysts over the last two decades, and they are broadly utilized in asymmetric catalysis. We report that achiral trisubstituted thioureas function as beneficial secondary ligands to CuI catalysts

A fluorine-containing tetrasubstituted stereogenic center is a highly valued structural feature in medicinal chemistry. Herein, we describe the direct coupling of racemic α-fluoronitriles and aldehydes promoted by a chiral CuI /Barton's base catalyt

A straightforward method is reported for the stereoselective anti-Markovnikov geminal diamination and stoichiometric geminal dioxygenation of vinylarenes mediated by a bromonium ion. The role of the substituent on the nucleophile and the nucleophilic

We report here the first general method for the geminal diamination and an intermolecular metal-free, geminal aminooxygenation of vinylarenes using hypervalent iodine reagent. A new m-CPBA mediated geminal aminooxygenation is also reported. A novel r

α-Halogenated carbonyl compounds are susceptible to dehalogenation and thus largely neglected as enolate precursors in catalytic enantioselective C-C bond-forming reactions. By merging the increased stability of the α-C-halogen bond of amides and t
