A three-step synthesis of (2Z), (4E)-polyenic acids 6 is described. Condensation of aldehydes 1 with potassium prenal enolate led to dihydropyranols 3 which were oxidized into dihydropyrones 5, precursors of (2Z), (4E)-polyenic acids 6. The procedure was applied to a synthesis of 13- cis-retinoic acids from β-ionylidene acetaldehydes. (C) 2000 Elsevier Science Ltd.
[3 + n] Annulation reactions by means of 3-trimethylstannyl-2-[(trimethylstannyl)methyl]propene, an isobutene dianion synthetic equivalent

Stepwise functionalization of the two carbon-tin bonds in 3-trimethylstannyl)-2[(trimethylstannyl)methyl]propene with electrophiles (diacyl dichlorides or aldehydes and carbon dioxide, provides a promising route for [3 + n] annulation reactions.
