N. Fokialakis et al., The structure of sarcomejine: An application of long-range H-1-N-15 correlation at natural abundance, J NAT PROD, 63(7), 2000, pp. 1004-1005
A new 4(1H)-quinolinone alkaloid, sarcomejine (1), has been isolated from t
he bark of Sarcomelicope megistophylla. Its structure has been elucidated o
n the basis of MS and NMR data and especially with a long-range H-1-N-15 co
rrelation NMR spectrum at natural abundance.
