✦ Synopsis

TRE synthesis and possible aromatic properties of monocyclic hydrocarbons formally containing alternating single and double bonds (vinylogs of benzene) have often been discussed.1 Nevertheless the only member of this series known up to now besides benzene itself is cyclo&?tatetraene, despite numerous synthetic attempts to prepare other members. We now describe the synthesis of cycloactadecanonaene (II) (for brevity named CON in this communioation), the first cyclic polyene after benzene which might be expected to exhibit aromatic properties since (a) it csn probably take up a planar or near planar configuration and (b) it

The new aromatic prostacyclin analog 3a and 3b were -synthesized from the allylic alcohol 5 in high regio-and stereoselectivity. Prostacyclin (PGI2, \_ 1) possesses the remarkable biological property of inhibiting the fatal effects caused by thromboxane A2. ' There is, however, an obstacle to the u
