In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called A Protocol for Metal Triflate Catalyzed Direct Glycosylation with GalNAc 1-OPiv Donors, published in 2014-11-21, which mentions a compound: 63295-48-7, Name is Iron(III) trifluoromethanesulfonate, Molecular C3F9FeO9S3, Recommanded Product: Iron(III) trifluoromethanesulfonate.
Herein we report on the development of novel glycosylation methodol. for the concise synthesis of naturally occurring glycoconjugate motifs containing N-acetylgalactosamine (GalNAc) from the cheaper and com. available N-acetylglucosamine (GlcNAc). The stereoselective glycosylation proceed with catalytic amounts of a promoter and without the need for N-protection other than the biol. relevant N-acetyl group. Among the catalysts explored, both Bi(OTf)3 and Fe(OTf)3 were found to be highly active Lewis acids for this reaction. It was also found that other less reactive metal triflates such as those of Cu(II) and Yb(III) can be beneficial in glycosylation reactions on more demanding glycosyl acceptors. We have furthermore demonstrated that it is possible to control the anomeric stereoselectivity in the glycosylation via post-glycosylation in situ anomerization to obtain good yields of α-galactosides. The present protocol was used to prepare important naturally occurring carbohydrate motifs, including a trisaccharide fragment of the naturally occurring marine sponge clarhamnoside.
This literature about this compound(63295-48-7)Recommanded Product: Iron(III) trifluoromethanesulfonatehas given us a lot of inspiration, and I hope that the research on this compound(Iron(III) trifluoromethanesulfonate) can be further advanced. Maybe we can get more compounds in a similar way.
