Visible-Light-Induced α,γ-C(sp3)-H Difunctionalization of Piperidines.

Organic Letters, 2022
Herein, we describe a novel protocol for visible-light-induced α,γ-C(sp3)-H difunctionalization of piperidines. This redox-neutral, atom-economical protocol, which exhibits a broad substrate scope and good functional group compatibility, constitutes a ...

Highly Diastereoselective Synthesis of Medium-Sized Carbocycle-Fused Piperidines via Sequential Hydride Shift Triggered Double C(sp3)-H Bond Functionalization.

Organic Letters, 2019
Herein we report a diastereoselective synthesis of medium-sized carbocycle-fused piperidines via [1,n (n = 6, 7)]-[1,5]-sequential hydride shift triggered double C(sp3)-H bond functionalization.

Catalytic Access to Bridged Sila- N-heterocycles from Piperidines via Cascade sp3 and sp2 C-Si Bond Formation.

Journal of the American Chemical Society, 2018
Described herein is the development of an unprecedented route to bridged sila- N-heterocycles via B(C6F5)3-catalyzed cascade silylation of N-aryl piperidines with hydrosilanes. Mechanistic studies indicated that an outer-sphere ionic path is operative to

Transition-Metal-Free Deconstructive Lactamization of Piperidines.

Angewandte Chemie, 2019
One of the major challenges in organic synthesis is the activation or deconstructive functionalization of unreactive C(sp3 )-C(sp3 ) bonds, which requires using transition or precious metal catalysts.
