Furthermore, the new Fmoc-2-MBT reagent is proposed for avoiding these side-reactions as well as the formation of the Fmoc-dipeptides (Fmoc-AA-AA-OH) and even tripeptides, which is another important side-reaction when chloroformates such as Fmoc-Cl is used for the protection of the -amino function of the amino acids.5 p.application/pdfeng(c) Wiley, 2007Reaccions químiquesSíntesi de pèptidsChemical reactionsPeptide synthesisFmoc-2-Mercaptobenzothiazole (MBT), for the Introduction of the Fmoc Moiety Free of Side-Reactionsinfo:eu-repo/semantics/article5491002013-12-20info:eu-repo/semantics/openAccess
