%X Turneforcidine has been prepared by the oxidation of methyl 7&#945;-hydroxy- 8&#945;-pyrrolizidine-1&#945;-carboxylate to the 7-keto compound and stepwise reduction with hydrogen/platinum and lithium aluminium hydride. 7&#946;- Hydroxy-8&#945;-pyrrolizidine-1&#946;-carboxylic acid is not epimerized by alkali but converted into the stable &#947;-lactone (VI).
