Reactivity and suitability of t-Boc-protected thiophosphotyrosine intermediate analogs for the solid or solution phase peptide synthesis

Preparation and determination of structure of L-3-deoxymimosine-containing peptides

L-3-Deoxymimosine-containing decapeptides were prepared for the development of protein tyrosine kinase (PTK) inhibitors. During the preparation of peptides, several side products were formed. Identification and determination of major peptides generated were reported.
