The structure of C‐alkaloid‐O ( 1 =his HCL‐salt) was established on the basis of spectral data and comparison with the analogous compound 2 , synthesized from a natural product of known absolute configuration. Internally consistent 13 C‐NMR. assignments are given for 1, 2 , huntrabrine methochloride (4) and its diacetate derivative 5 .
