According to-Vellard, a Strychnos sp. similar to S. medeola is used by the Nambikwaras. Brasil, Campos and Kuhlmann have mentioned three S. American species of Strychnos, viz., S. diplinerva, S. off. albiflora Prog and S. brevifolia A.D.C., in which, using extracts of the roots in comparison with Tecuna curare, they have found curarising activity by pharmacological tests in rabbits.

The regioselectivity observed in these reactions can be correlated with the resonance structure shown in Fig. 2. The reaction with electron-rich or electron-poor alkynes leads to intermediates which are the expected on the basis of polarity matching. In Fig. 2 is represented the reaction with an ynone leading to a metalacycle intermediate (formal [4C+2S] cycloadduct) which produces the final products after a reductive elimination and subsequent isomerisation. Also, these reactions can proceed under photochemical conditions. Thus, Campos, Rodriguez et al. reported the cycloaddition reactions of iminocarbene complexes and alkynes [57,58], alkenes [57] and heteroatom-containing double bonds to give 2Ff-pyrrole, 1-pyrroline and triazoline derivatives, respectively [59].
