Cyclo­(-L-prolyl-L-valinyl-) from Burkholderia thailandensis MSMB43

X.-Y. Liu, C. Wang and Y.-Q. Cheng

Abstract: The title compound [systematic name: (3S,8aS)-3-isopropyl­hexa­hydro­pyrrolo­[1,2-a]pyrazine-1,4-dione], C10H16N2O2,, is a newly isolated cyclic dipeptide from Burkholderia thailandensis MSMB43. There are two independent mol­ecules in the asymmetric unit. Two C atoms and their attached H atoms in the five-membered ring of one of the mol­ecules are disordered over two sets of sites in a 0.715 (5):0.285 (5) ratio. The two independent mol­ecules have the same configuration and the absolute configurations of the chiral centers were determined based on the observation of anomalous dispersion. In the crystal, two types of N-H...O hydrogen bonds link pairs of independent mol­ecules.
