New Heterocyclic Amino Acid Building Blocks
 
The Squarix Newsletter provides you with information about our innovative building blocks, reactive intermediates and screening compounds from our Discovery Chemicals portfolio.
 
In this issue we present new heterocyclic amino acid building blocks especially designed for stereocontrolled synthesis of peptidomimetics and new platforms for supramolecular chemistry.

Please find also some selected references from the literature describing interesting applications of our new building blocks. (-)-Muscoride A, a bioxazole peptide alkaloid was synthetized by Wipf and Venkatraman using the key building block PM030. Haberhauer et al. reported an efficient syntheses of C2-symmetric macrocyclic receptors using the imidazol building block PM139 as starting material.
