Quaternary Carbon Editing Enabled by Sequential Palladium Migration

Qian Wang, Jieping Zhu, Takuji Fujii, Hua Wu

Peripheral functionalization of a quaternary carbon via C(sp 3)−H bond activation has made significant progress in recent years. However, direct editing of a quaternary carbon through Csp 3 −Csp 3 bond cleavage and refunctionalization of nonstrained acycli ...

Editing Tetrasubstituted Carbon: Dual C–O Bond Functionalization of Tertiary Alcohols Enabled by Palladium-Based Dyotropic Rearrangement

Qian Wang, Jieping Zhu, Baochao Yang, Tristan Corentin Pierre Delcaillau

Many elegant asymmetric syntheses of enantioenriched tertiary alcohols have been developed, and both the transition metal-catalyzed and the radical-based peripheral functionalization of tertiary alcohols have attracted intensive research interest in recent ...

Arylative Ring Expansion of 3-Vinylazetidin-3-Ols and 3-Vinyloxetan-3-Ols to Dihydrofurans by Dual Palladium and Acid Catalysis

Qian Wang, Jieping Zhu, Takuji Fujii

In contrast to the well-studied 1-vinylcyclobu- tanols, the reactivity of 3-vinylazetidin-3-ols 1 and 3- vinyloxetan-3-ols 2 under transition metal catalysis remains largely unexplored. We report herein their unique reactivity under dual palladium and acid ...

Catalytic Enantioselective Synthesis of Inherently Chiral Macrocycles by Dynamic Kinetic Resolution

Jieping Zhu, Shuo Tong

Kinetically fast racemization of chiral substrates through an achiral intermediate and enantioselective functionalization of one of the enantiomeric substrates forms the basis of the dynamic kinetic resolution (DKR) of centrally chiral molecules. We report ...

Chemoselective Pd-Based Dyotropic Rearrangement: Fluorocyclization and Regioselective Wacker Reaction of Homoallylic Amides

Qian Wang, Jieping Zhu, Chenxu Liu

Fluorocyclization of alkenes tethered with a pronucleophile is an efficient transformation that converts easily accessible starting materials to fluorinated heterocycles in a single step. We report herein an unprecedented Pd(II)-catalyzed oxidative domino ...

Design and Synthesis of C4‐Symmetric Axially Chiral β‐Aryl Porphyrins and Application for Supporting Ir(III)‐Catalyzed Enantioselective C−H Alkylation

Jieping Zhu

A hitherto unknown class of C4-symmetric Caryl Cβ (C3, C8, C13, C18) axially chiral porphyrins has been synthesized and the application of their iridium (Ir) complexes in catalytic asymmetric C(sp3) H functionalization is documented. Cyclotetramerization o ...

[4+1] Heteroannulation to Form 1‐Pyrrolines through Alder‐Ene Reaction of in situ Generated Ynimines: Development and Application in Total Synthesis of Borrecapine

Qian Wang, Jieping Zhu, Rémi Hugo Lavernhe

We report in this paper a novel Cu-catalyzed synthesis of polysubstituted 1-pyrrolines. The reaction of β,γ-unsaturated oxime esters 4 with terminal alkynes 5 in the presence of a catalytic amount of Cu(OAc)2 and 2,2’-biquinoline affords the corresponding ...

Inherently chiral nor-heteracalixarenes: design and synthesis via enantioselective intramolecular Suzuki-Miyaura reaction

Jieping Zhu, Shuo Tong

There has been a recent upsurge in research aimed at synthesizing inherently chiral molecules devoid of point, axial, planar and helical chiralities. We present herein our design and enantioselective synthesis of a series of inherently chiral macrocycles. ...

Benzylic C(sp3)-H Azidation: Copper vs Iron Catalysis

Qian Wang, Jieping Zhu, Jérôme Waser, Pierre Gérard Joseph Palamini, Raphaël Michel Henri Simonet-Davin

The generation of benzylic radicals through hydrogen atom abstraction (HAT) has been a recent research focus and various C(sp(3))-H bond functionalization protocols have been developed relying on this elementary step. We report herein copper- and iron-cata ...

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

Qian Wang, Jieping Zhu, Qiang Feng, Chenxu Liu

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 ...
