摘要

Octafluorotoluene reacts with the enone function of andro~t-4-ene-3~17-dione in the presence of caesium fluoride to give specifically a 3,5-dienol ether which has been used to prepare deuterium-labelled testosterone. ... We have recently demonstrated the use of heptafluoro-p-tolyl for the selective protection of phenolic and alcoholic func- tionsl and applications in the synthesis of analogues of the anti-cancer drug tamoxifen.2.3 The phase transfer ...
