Organocatalytic Enantioselective Pictet–Spengler Reaction of α‐Ketoesters: Development and Application to the Total Synthesis of (+)‐Alstratine A

Qian Wang, Jieping Zhu, Rémi Julien Sylvain Andres, Fenggang Sun

We report herein an asymmetric Pictet– Spengler reaction of α-ketoesters. In the presence of a catalytic amount of simple alanine-derived squaramide and p-nitrobenzoic acid, reaction of tryptamines with methyl 2-oxoalkanoates afforded the corresponding 1- ...

High-affinity peptides developed against calprotectin and their application as synthetic ligands in diagnostic assays

Christian Heinis, Florence Pojer, Lluc Farrera Soler, Kelvin Ka Ching Lau, Cristina Diaz Perlas

A peptide was developed that binds to calprotectin, a marker of major inflammatory disorders, and found to be suited for diagnostic tests. The use of synthetic peptides in assays is of great interest due to their high precision, robustness and low price. ...
