D-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.


Solid-Phase Synthesis of an “Inaccessible” hGH-Derived Peptide Using a Pseudoproline Monomer and SIT-Protection for Cysteine; S. R. Manne, A. Chakraborty, K. Rustler, T. Bruckdorfer, B. G. de la Torre, F. Albericio; ACS Omega 2022; 7(32): 28487–28492.

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.
