Dodecahydro-8a-nitro-as-indacen-4(2H)-one, dodecahydro-9a-nitro-4H-benzinden-4-one, dodecahydro-9b-nitro-5H-benzinden-5-one and dodecahydro-4a-nitro-9(1H)-phenanthrenone of cis-anti-cis backbone are synthesized in quantitative yield by cycloaddition reaction of 1-nitro-cyclopent-1-ene and 1-nitro-cyclohex-1-ene with 1-(cyclopenten-1-yl)- and 1-(cyclohexen-1-yl)-1-(piperidin-1-yl)-ethenes respectively.The enamine intermediates are also isolated and characterized.
