A mixture of D : B-friedo-bacchar-5(10)-en-3-one (<B>2</B>) and D : B-friedo-bacchar-5-en-3-one (<B>4</B>), prepared from 4α-bromoshionan-3-one (<B>3</B>) by the known procedures, was converted into a mixture of 2ξ-bromo-D : B-friedobacchar-5(10)-en-3-one (<B>6</B>) and 2ξ-bromo-D : B-friedo-bacchar-5-en-3-one (<B>7</B>) by bromination with pyridinium tribromide. The mixture (<B>6</B> and <B>7</B>) was subjected to dehydrobromination to give D : B-friedo-bacchara-1,5(10)-dien-3-one (<B>5</B>). Hydrogenation of the dienone (<B>5</B>) gave D : B-friedo-bacchar-5(10)-en-3-one (<B>2</B>).
