The structure of folisine

  • Published:
Chemistry of Natural Compounds Aims and scope

Summary

  1. 1.

    From the mixture of alkaloids ofH. foliosum has been isolated a new base — folisine — which is 1-methyl-α,β-dihydrofurano-4-quinolone with a substituting group on the α-carbon atom.

  2. 2.

    The transition from dubinidine to folisine has been effected by the reaction of dubinidine methiodide with anhydrous pyridine.

  3. 3.

    When dubinidine is heated with methyl iodide in a sealed tube, the usual isomerization takes place and folisine is formed.
