New modulators of estradiol receptors were synthesized, 17(gamma-alkoxy-3-oxo-8-isoestr-5(10)-enes) and the respective D-homoanalogs. Reaction of these compounds with CuBr2 in acetonitrile famished steroids with aromatic A ring possessing hypocholesterolemic and osteoprotective activity.
Totally synthetic steroid hormones. XII The preparation and catalytic hydrogenation of novel (±)-estra-1,3,5(10), 8,14,16-hexaenes and (±)-13-ethylgona-1,3,5(10),8,14,16-hexaenes
