Abstract
PURPOSE: Title compound useful as an intermediate for 4-homoisotwistan and as physiologically active such as antibiral active substances is prepared from bicyclo [3.3.0]octane-endo-2-carbonyl halide as a starting material.
CONSTITUTION: As shown by reaction equations, diazomethane is made to act on bicyclo[3.3.0]octane-endo-2-carbonyl halide of formula II (X is Cl, Br) and the resulting diazoketone derivative of formula III is subjected to thermal decomposition in the presence of a cupric compound such as cupric oxide, halide, sulfate or acetate to produce the objective perhydrotriquinacene-2-one of formula I. Further, 4- homotwistane of formula IV, the derivative of which is known to have excellent antiviral activity, is derived from the resulting product in high selectivity.
