2-乙酰基-5-降冰片烯 | 2-acetyl-5-norbornene | 5063-03-6 | C9H12O | 136.194 |
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 3,17β-dihydroxy-6-oxaoestra-1,3,5(10),8(9)-tetraen-7-one (11). Compounds (3a) and (11) were tested for oestrogenic activity.
