Novel method for reductive cleavage of triterpenoid lactones with lithium in ethylenediamine

Sterically hindered γ-lactones furnish mainly the saturated carboxylic acids whereas δ-lactones with less hindrance yield the diols in higher percentage compared to the acids. ε-Lactones, however, furnish the diols exclusively.The reduction is drastic and effective when other methods fail.
