- New retinoid analogs from δ-pyronene, a natural synthon
-
δ-Pyronene (1), a readily available terpenic synthon, is an excellent raw material for the preparation of numerous terpenic intermediates. Original retinoid analogs such as 'iso'-retinyl acetate (5), 'iso'-retinal (6) and ethyl 'iso' retinoate (7), in which the cyclogeranyl moiety is functionalized in an unusual position, were prepared from δ-pyronene.
