The total synthesis of two natural acetylenic aromatic carotenoids, 7,8-didehydroisorenieratene (<B>1</B>) and 7,8-didehydrorenieratene (<B>2</B>), was carried out. Although the condensations involving C<SUB>15</SUB>-acetylenic ylids (derived from the phosphonium salts <B>7</B>, and <B>8</B>) as the intermediates gave only 9-<I>cis</I> isomers of <B>1</B> and <B>2</B>, low-temperature condensations of C<SUB>25</SUB>-hexaene yield (derived from <B>19</B> and <B>28</B>) with C<SUB>15</SUB>-acetylenic aldehyde (<B>12a</B>) led to all-<I>trans</I> <B>1</B> and <B>2</B>, which were identical with natural specimens.
