Synthesis of monoterpene piperidines from the iridoid glucoside antirrhinoside
Synthesis of five novel piperidine monoterpene alkaloids using the iridoid glucoside antirrhinoside as a synthon is described. Two strategies for their preparation were investigated: the first possible pathway involved an intermediate diol from which the piperidine ring was expected to be constructed via reaction of its ditosylate with an amine; the second strategy involved a double reductive amination as the key step to the piperidine ring, which proved successful.
The stereochemistry of C-5 and C-9 in the obtained piperidine monoterpenes was the same as that reported for alfa-Skytanthine, a known isolate from Skytanthus acutus (Apocynaceae).
