Highly stereoselective eliminations were achieved by acid-catalysed dehydration of 1-(4-alkoxy)-3,3,3-trifluoro-1,2-diphenylpropan-1-ols (10, 11, 15). The influence of the trifluoromethyl group on the stereochemistry of the elimination has been discussed. The observed high stereoselectivity has been applied to give a new, practical synthesis of antiestrogenic drug panomifene (1).
