Mao, Runyu;Xi, Shiyi;Shah, Sayali;Roy, Michael J.;John, Alan;Lingford, James P.;Gade, Gerd;Scott, Nichollas E.;Goddard-Borger, Ethan D. research published 《 Synthesis of C-mannosylated glycopeptides enabled by Ni-catalyzed photoreductive cross-coupling reactions》, the research content is summarized as follows. The biol. functions of tryptophan C-mannosylation are poorly understood, in part, due to a dearth of methods for preparing pure glycopeptides and glycoproteins with this modification. To address this issue, efficient and scalable methods are required for installing this protein modification. Here, we describe unique Ni-catalyzed cross-coupling conditions that utilize photocatalysis or a Hantzsch ester photoreductant to couple glycosyl halides with (hetero)aryl bromides, thereby enabling the α-C-mannosylation of 2-bromo-tryptophan, peptides thereof, and (hetero)aryl bromides more generally. We also report that 2-(α-
Computed Properties of 73724-45-5, Fmoc-Ser-OH, also known as Fmoc-Ser-OH, is a useful research compound. Its molecular formula is C18H17NO5 and its molecular weight is 327.3 g/mol. The purity is usually 95%.
Fmoc-L-Ser-OH is a synthetic peptide that belongs to the group of glycopeptides. It is used as a model for such compounds and has been shown to have antimicrobial activity in vitro against gram-positive bacteria, especially Staphylococcus epidermidis. This compound was synthesized from 3-mercaptopropionic acid and chloride in the presence of hydroxyl groups and epidermal growth factor. The synthetic pathway can be divided into three steps: (1) condensation of 3-mercaptopropionic acid with hydrochloric acid to yield 3-mercaptoacrylic acid; (2) esterification of 3-mercaptoacrylic acid with glycine to form Fmoc-L-Ser; and (3) deprotection of Fmoc protecting group., 73724-45-5.
