The authors wish to make the following correction to this paper [1].
Error in Schemes
In the original publication, there was a mistake in Scheme 8 as published. The old version Scheme 8 does not specify that the last product is a peptide sequence. The corrected Scheme 8 appears below.
Scheme 8.
N-alkylation of nosyl-protected Fmoc-amino acid promoted by activated 4 Å MS.
In the original publication, there was a mistake in Scheme 10 as published. The old version of Scheme 10 is not clear concerning the inserted functional group and the side chain of the amino acids. The corrected Scheme 10 appears below.
Scheme 10.
Chemoselective S-alkylation of a peptide sequence promoted by activated 4 Å MS.
In the original publication, there was a mistake in Scheme 11 as published. The old version of Scheme 11 contains a mistake regarding the protecting group of the Arginine residue, where Pbf was written instead of Boc. The corrected Scheme 11 appears below.
Scheme 11.
Solid-phase S-alkylation of peptide sequences anchored on resin promoted by activated 4 Å MS.
The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
