Ijc. Vieira et al., Complete H-1 and C-13 chemical shift assignments of a new C-22-quassinoid isolated from Picrolemma sprucei Hook by NMR spectroscopy, MAGN RES CH, 38(9), 2000, pp. 805-808
The H-1 and C-13 NMR spectra of a new C-22-quassinoid from Picrolemma spruc
ei were completely assigned. In addition to conventional 1D NMR, a variety
of 2D shift-correlated NMR experiments [H-1 x H-1-COSY, H-1 x C-13-HMQC-(1)
J(C,H), H-1 x C-13-HMBC-(n)J(C,H) (n = 2 and 3) and 2D H-1 x H-1-NOESY] was
used. Copyright (C) 2000 John Wiley & Sons, Ltd.
