Investigations of metal-coordinated peptides as supramolecular synthons
Gerhardt, Warren W.,Weck, Marcus
, p. 6333 - 6341 (2006)
This article describes the synthesis and controlled assembly of four model biological-hybrid scaffolds via coordination of a metal complex to four new tripeptides. Each model tripeptide investigated has either a central pyridyl glycyl or a pyridyl alanyl
Investigating Bicyclobutane-Triazolinedione Cycloadditions as a Tool for Peptide Modification

Acyl bicyclobutanes are shown to engage in strain-promoted cycloaddition reactions with a diverse array of triazolinedione reagents. The synthesis of an orthogonally protected urazole building block enabled the facile preparation of amino acid- and peptid
A general method for the facile synthesis of optically active 2-substituted piperazines via functionalized 2,5-diketopiperazines

Upon utilization of some common methods described in the literature for the synthesis of chiral, 2-substituted 2,5-diketopiperazines, extensive racemization was observed. Further investigation showed that heating in the presence of a mild base racemized the chiral center in the product diketopiperazines. A generalized, readily scalable route was sought and, after investigating the effect of base and temperature, conditions were identified that promoted cyclization without erosion of enantiomeric excess. An array of functionalization was tolerated and this procedure serves as a useful and reliable method for the facile synthesis of this important class of compounds.
