Rollover Cyclometalation as a Valuable Tool for Regioselective C–H Bond Activation and Functionalization

open access: yesMolecules, 2021
Rollover cyclometalation constitutes a particular case of cyclometallation reaction. This reaction occurs when a chelated heterocyclic ligand loses its bidentate coordination mode and undergoes an internal rotation, after which a remote C–H bond is ...

Synthesis of Benzo[4,5]thiazolo[2,3-c][1,2,4]triazole Derivatives via C-H Bond Functionalization of Disulfide Intermediates [PDF]

open access: yesMolecules, 2022
Many nitrogen- and sulfur-containing heterocyclic compounds exhibit biological activity. Among these heterocycles are benzo[4,5]thiazolo[2,3-c][1,2,4]triazoles for which two main synthetic approaches exist.

Site-Selective C─H Bond Functionalization of Sugars. [PDF]

open access: yesAngew Chem Int Ed Engl
Abstract Non‐typical C‐functionalized sugars represent a prominent yet hardly accessible class of biologically‐active compounds. The available synthetic methodologies toward such sugar derivatives suffer either from an extensive use of protecting groups, requiring long and laborious synthetic manipulations, or from limited ...

Transition-metal-free electrochemical-induced active C(sp3)-H functionalization

open access: yesGreen Chemistry Letters and Reviews, 2023
Direct C–H bond functionalization is the most effective technique to construct C–X (X = C, N, O, S, etc.), which could simplify the conventional synthesis methods.
