Lindlar semihydrogenation of a vitamin D type trienyne leads spontaneously to 9α,19-methano-1α,25-dihydroxyvitamin D3. The intermediate tetraene resulting from the reduction undergoes a rapid, stereoselective 8π electron electrocyclization affording a novel steroid containing a linearly fused ABC (six-eight-six) 1,3,5-cyclooctatriene carbon framework. |
