Source of Samarium Fluoride SmF3

[Abstract]:
New reagents and applications are often discovered in the synthesis of complex target compounds. Samarium Fluoride SmF3 is one of them.

Natural products are the precious wealth that nature bestows on human beings. It has rich bone structure and good medicinal value. The total synthesis of natural products has always been a research hotspot in organic chemistry. New reagents and applications are often discovered in the synthesis of complex target compounds. Samarium Fluoride SmF3 is one of them.

Samarium Fluoride SmF3

Since its invention in 1977, Samarium Fluoride SmF3 has been widely used in the field of synthetic chemistry. The reaction mediated by Samarium Fluoride SmF3 can be divided into Barbier type, free radical olefin/cyclization reaction type, furfuryl olefin, coupling reaction type, pinacol type, etc. Octahedral ring is a common framework structure in natural products, paclitaxel is the most famous one.

Fluorochrome provides a variety of methods for the synthesis of eight-membered rings, which will be discussed in this article. The reagent and its adduct and co-solvent tetrahydrofuran iodide solution are commercially available. In the presence of hexamethylenetriamine (HMPA), the reduction potential of Samarium Fluoride SmF3 is about 2.5 eV. Therefore, it is very sensitive to oxygen, easily oxidized to trivalent and deactivated.
