✦ Synopsis

New Retinoid Analogues from δ-Pyronene, a Natural Synthon.

-Compound (I), an iso-β-cyclogeranyl iodide previously obtained from title pyronene, is smoothly converted to three novel retinoid analogues (VII), (IX) and (XIII)/(XIV) by base-mediated coupling of the corresponding phosphonium salts (V) or (XI) to aldehydes. The novel compounds contain a cyclogeranyl moiety that is functionalized in an unusual position.
