15,16-Dihydro-17-oxocyclopenta[a]phenanthrene and its 3-methoxy, 11- and 12-methyl, and 11,12-dimethyl, derivatives have been synthesised by aromatisation of the 3-unsubstituted and 3-methoxy-11,17-diketones in which rings C and D are both saturated; the mechanism of the aromatisation is discussed.
通过将3-未取代的和3-甲氧基-11芳构化,合成了15,16-二氢-17-氧代环戊[ a ]菲及其3-甲氧基,11-和12-甲基以及11,12-二甲基衍生物。C,D环均饱和的,17-二酮;讨论了芳构化的机理。

the Δ15– 17H-compound (A), but at 100° the Δ16– 15H-isomer was formed. Base-catalysed condensation of (A) with acetone and aryl aldehydes yielded 17-substituted-methylene derivatives. The chemical shifts of protones attached to ringD in these compounds are listed.
