hofmann degradation of alkaloids

The saturation of two double bonds introduced during this degradation gives a tetrahydromethine that can be converted into a monomethiodide, the Hofmann degradation of which proceeds with the loss of trimethylamine and the production of des-N(a)-emetinetetrahydromethine. 2 publications.
