Oxidative rearrangement of 1,1-disubstituted alkenes to ketones

Qian Wang, Jieping Zhu, Qiang Feng

The Wacker process, which is widely used to convert monosubstituted alkenes into the corresponding methyl ketones, is thought to proceed through a PdII/Pd0 catalytic cycle involving a b-hydride elimination step. This mechanistic scenario is inapplicable to ...

Organocatalytic Double Ugi Reaction with Statistical Amplification of Product Enantiopurity: A Linker Cleavage Approach To Access Highly Enantiopure Ugi Products

Jieping Zhu, Shuo Tong, Qiang Feng

Here we report an organocatalytic double Ugi reaction combining the enantioselective process and ee enhancement in a single operation to afford the chiral Ugi products with very high ee values. Both bisisocyanides and bisanilines tethered by carbonate and ...

Palladium‐Based Dyotropic Rearrangement Enables A Triple Functionalization of Gem‐Disubstituted Alkenes: An Unusual Fluorolactonization Reaction

Chenxu Liu, Qiang Feng, Jieping Zhu, Qian Wang

We report in this paper a Pd(II)-catalyzed migratory gem-fluorolactonization of ene-carboxylic acids. Reaction of 4-methylenealkanoic acid derivatives with Selectfluor in the presence of Pd(OAc)2 (1.0 mol %) at room temperature affords fluorolactones in go ...

Catalytic Enantioselective Synthesis and Switchable Chiroptical Property of Inherently Chiral Macrocycles

Jieping Zhu, Shuo Tong, Xianfu Zhang, Qiang Feng

We report herein a strategy to construct enantiopure inherently chiral macrocycles, ABCD-type heteracalix[4]-aromatics, through a catalytic enantioselective intramolecular C−N bond forming reaction. A chiral ligand-palladium complex was found to efficientl ...
