The acid-mediated cleavage of a synthetic thioxo peptide was monitored using deprotection cocktails with varying concentrations of TFA. Thioxo peptides are acid labile, undergoing cleavage at the amide linkage immediately following the thioamide linkage in the sequence. This acid lability makes Fmoc

The reduction of methionine sulfoxide with Bu 4 NBr in TFA is reported. The use of this reagent in conjunction with Fmoc chemistry-based acidolytic cocktails and the short reaction times that are needed for sulfoxide reduction (5 min) are the main advantages of this method, which is compatible with
