“…The latter proved to be identical with the product obtained from the catalytic reduction of Á6-androstene-30,16 , 170-triol triacetate. 5,6 Although this reaction sequence completed the model study for the synthesis of estriol, the structure of (he products and intermediates must be discussed in order to clarify the points of similarity and difference between these reactions and those described in the preceding report.7…”
