                                The preparation of 2,4-dibromoestra- 1,3,5(10),6-tetraene-3,17 β-diol diacetate
                             
                            
                                摘要:
                                [2,4,6,7-H-3(4)]Estradiol is used for the quantitative determination of estradiol receptors.  The synthesis of 2,4-dibromoestra-1,3,5(10),6-tetraene-3,17-beta-diol 3,17-diacetate, the convenient precursor of [2,4,6,7-H-3(4)]estradiol, is described.  6-Alkoxy compounds were also prepared and investigated.
