An enantiospecific totalsynthesis of indolealkaloids eburnamonine, aspidospermidine and quebrachamine is described from lactic acid. Synthesis of all three alkaloids is accomplished from a single chiral building block. Johnson–Claisen rearrangement of a chiral allyl alcohol is the main feature for the installation of the required quaternary centre.
