The circular dichroism spectra of bakers' yeast l-lactate dehydrogenase and some of its derivatives (without flavin and/or heme) have been investigated in order to obtain some information about the interactions between the prosthetic chromophores or between these chromoph...
We realized here two approaches toward the common skeleton of these alkaloids based on a radical cascade reaction as key-step. The first one is particularly original implying a radical cyclisation followed by Smiles’rearrangement aiming at the tetracyclic ring system (C, D, E, F) of these ...

The quantitative analysis has shown that (i) practically all the information (90–95%) is provided by the plagiotropic branches (their length, the length of their internodes; dimension and number of their leaves) and by the pollen (dimensions); (ii) the various taxons of the subsection ...
