OLEFINIC AND ACETYLENIC COMPOUNDS. V. THE REGIOSPECIFIC SYNTHESIS OF 1,5-DISUBSTITUTED-CYCLOOCTATETRAENE DERIVATIVES.
The thermally controlled addition of methylpropiolate or cyanoacetylene to 1-methoxycarbonyl- or 1-cyano-quadricyclanone leads in a regiospecific way to the corresponding 1,5-disubstituted cyclooctatetraenes.
