Notes:
The cyclodipeptides cyclo(L-alanyl-L-phenylalanyl) and cyclo(D-alanyl-L-phenylalanyl) were synthesized with various atoms substituted by the isotopes 15N and 13C. Thus, the coupling constants 15N-1H, 13C-1H, and 13C-15N could be obtained, in addition to the commonly used 1H-1H constants. The applicability of these coupling constants for obtaining conformational information on side chains and substituted 2,5-piperazinedione rings is discussed.
