Abstract
Two procedures were developed for the synthesis of 17α-alkyl-8α,9β-estra-1,3,5(10)-triene-3,14β,17β-triols from 3-methoxy-estra-1,3,5(10),8(9),14(15)-pentaene-17-one (1) using photosensitized oxidation by atmospheric oxygen or ionic hydrogenation in the presence of oxygen. It was shown that 17α-hexynyl-8α,9β-estra-1,3,5(10)-triene-3,14β,17β-triol (23) and its 3-methoxy derivative (26) inhibit K+,Na+-ATPase, with inhibition degree increasing on introduction of an oxygen-containing substituent into position 17. For the first time steroids were found with α2-adrenoblocking action.
