摘要：
Cyclo-[(S)-His-(S)-Leu] adopts a conformation in solution in which the imidazole ring is folded over the diketopiperazine ring. This is the opposite conformation to that determined for cyclo-[(S)-His-(S)-Phe], and may explain the opposite sense of asymmetric induction between the two catalysts.
