A convenient procedure was developed for the preparation of N-deacetyllappaconitine by acid hydrolysis of lappaconitine. The crystal and molecular structures of by-products of acid hydrolysis of lappaconitine, viz., 14- and 16-demetliyl-N-deacetyllappaconitines, were established by X-ray diffraction analysis. Azocoupling of diazonium chlorides that were prepared from lappaconitine N-deacetylation products with beta-naplithol afforded the corresponding 1,2-naphthoquinone 1-hydrazones.

Lappaconitine and N-deacetyllappaconitine derivatives containing bromine and iodine atoms in the aromatic moiety were synthesized. The Heck cross-coupling of these halides with ethyl acrylate or 2-methyl-5-vinylpyridine afforded new olefinated lappaconitine derivatives.
