Thiolation of symmetrical and unsymmetrical diketopiperazines
Org. Biomol. Chem., 2012The introduction of sulfur units into a variety of symmetrical and unsymmetrical diketopiperazines (DKPs) is described. We investigated different thiolation methods utilizing several bases and electrophilic sulfur reagents, leading to monomethylthio-, bis(methylthio)-, and epithio-DKPs.

Discovery of a Class of Diketopiperazines as Antiprion Compounds
ChemMedChem, 2010AbstractPrion diseases are fatal neurodegenerative and infectious disorders for which effective pharmacological tools are not yet available. This unmet challenge and the recently proposed interplay between prion diseases and Alzheimer's have led to a more urgent demand for new antiprion agents.

The Infrared Dichroism of Diketopiperazine
The Journal of Chemical Physics, 1951The absorption of polarized infrared radiations by diketopiperazine crystal has been measured in the wavelength region from 2.8 to 15μ. From the observed infrared dichroism the assignment of the absorption bands has been made.

Asymmetric hydrogenations of diketopiperazines
Topics in Catalysis, 2000The dehydrodiketopiperazines 6 undergo face selective hydrogenation with a 5% palladium on carbon catalyst to give the diketopiperazines 7 in high yield with excellent diastereoisomeric ratios (>97%).
