Syntheses of the alkaloids eburnamonine and quebrachamine are presented in which the non-tryptamine portion of the skeleta is constructed by the β-oxycyclopropylcarboxylate preparation-fragmentation route. A similar reaction scheme is utilized for the synthesis of the alkaloids vincadine and epivincadine.
