9,11-Secoestradiol derivatives having a hydroxyl group at C-11 or a 11-oic acid undergo facile cyclisation at C-17 giving corresponding 11,17-oxides.Formation of 3-methoxy-11-oxo-9,11-secoetrane-11,17-oxide (2), 3-methoxy-9,11-secoestrane-11,17-oxide (3), 3-methoxy-11-methyl-9,11-secoestrane-11,17-oxide (5) and 3-methoxy-11,11-dimethyl-9,11-secoestrane-11,17-oxide (7) is reported.Stereochemical assignements have been made on the basis of PMR (400 MHz), BB proton decoupled, SFORD, DEPT and selective heteronuclear spin decoupling 13C NMR experiments.The effect of cyclisation involving 17-OH group on in vitro receptor binding affinity to estradiol receptors and estrogenicity in rats (in vivo) have also been evaluated.
