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%).
