N2  - A Pechmann condensation of resorcinol, or resorcinol monomethyl ether with ethyl t-7a-methyl- 1,5-dioxo-r-3a,4,5,6,7,7a-hexahydroindan-c-4-carboxylate (10b) gave 3-hydroxy-6-oxaoestra- 1,3,5(10),8(9)-tetraene-7,17-dione (3a), or the corresponding 3-methoxy compound (3b), respectively. Reduction of 3-hydroxy-6-oxaoestra-1,3,5(10),8(9)-tetraene-7,17-dione (3a) with sodium borohydride gave 3,17&#946;-dihydroxy-6-oxaoestra-1,3,5(10),8(9)-tetraen-7-one (11). Compounds (3a) and (11) were tested for oestrogenic activity.
