FLEXIBILITY OF SUPPOSED “RIGID” MOLECULES: SUBSTITUTED 2,5-PIPERAZINEDIONES (DIKETOPIPERAZINES)

The relevant results of accurate X-ray analyses of both the trans-and the L-cis-3,6-dimethyl-2,5-piperazinediones (diketopiperazines) are reported. We note that a large variability of conformations for the ring system can be accomplished by coupling small bond-angle deformations with large variation...
