In continuation of our previous investigation of the C NMR spectroscopy of the Strychnos alkaloids,' the chemical shifts caused by hydroxy and methoxy sub- stituents in the aromatic ring of the strychnine (1-10) and Nb-methyl-s-pseudostrychnine (11-15) types of ... 11 Icajine; R = R, = R, = R, = H, 12 Vomicine; R = R1 = R, = H, R2 = OH, A19 13 19,20-a-Epoxy-15-hydroxyicajine; R = R1 = R, = ... The spectra were recorded in ...
