Copper supported Mg Al hydrotalcite derived oxide catalyst for enol carbamates synthesis via C H bond activation of formamides

Copper-catalyzed intermolecular C(sp3)-H bond functionalization towards the synthesis of tertiary carbamates.

We describe the development of an intermolecular unactivated C(sp3)-H bond functionalization towards the direct synthesis of tertiary carbamates. The transformation proceeded using a readily available, abundant first-row transition metal catalyst (copper), and isocyanates as the source of the amide moiety. This is a novel strategy for direct transformation of a variety of unactivated hydrocarbo...

C-C bond formation via C-H bond activation: synthesis of the core of teleocidin B4.

The core of teleocidin B4, a complex fragment of a natural product containing two quaternary stereocenters and a penta-substituted benzene ring, was synthesized in four C-C bond-forming steps starting from tert-butyl derivative 1. The first step involved alkenylation of the tert-butyl group with a vinyl boronic acid, followed by the successful annulation of the cyclohexane ring to the benzene n...

A versatile ruthenium catalyst for C-C bond formation by C-H bond activation.

Transesterification Of Sunflower Oil Using Mg-Al- Co3 Hydrotalcite As A Catalyst

An efficient and facile synthesis of fatty acid methyl esters (FAMEs) using sunflower oil and methanol has been carried out in the presence of a solid base Mg-Al-CO3 hydrotalcite heterogeneous catalyst. This protocol promotes the environment friendly conditions as the hydrotalcites are non toxic, recyclable, takes less reaction time and is easy to work up. The hydrotalcite showed high activity ...
