A Novel Synthesis of Pyrrolizidine Alkaloids by Means of an Intramolecular Carbenoid Displacement (ICD) Reaction

The pyrrolizidine alkaloids, (+/-)-trachelanthamidine, (+/-)-isoretronecanol, and (+/-)-supinidine were synthesized by using an intramolecular carbenoid displacement (ICD) reaction of the diazo-sulphide or the diazo-selenide derivatives as a key step.
