Threonine-derived Pseudoproline monomer for SPPS. This building-block can be successfully coupled with many amino-acids using modern coupling techniques avoiding the need for pseudoproline dipeptides and giving the possibility to introduce pseudoprolines in peptides containing non-natural or rare amino-acids. For coupling efficiency studies, please refer to the listed reference.
Scope and limitations of pseudoprolines as individual amino acids in peptide synthesis; D. A. Senko, N. D. Timofeev, I. E. Kasheverov, I. A. Ivanov; Amino Acids 2021; 53: 665-671. https://doi.org/10.1007/s00726-021-02973-1.
