Elemadienolic acid has been converted into the acetoxy-phenol-lactone XXXV, which is enantiomeric to the corresponding compound (XXII) obtained from lanosterol (XVII). This result represents the final proof of the structure and configuration of elemadienolic acid shown in formula XV and eo ipso of the related compounds euphol (I), tirucallol (IV), elemadienonic acid (VIII) and euphorbol (XVI).
