Biomimetic polyene cyclizations

Bioorganic Chemistry, 1976
AbstractCertain polyenic substances having trans olefinic bonds in a 1,5 relationship can be induced to undergo stereospecific, non‐enzymic, cationic cyclization to give polycyclic products with all‐trans (“natural”) configuration. These transformations appear to mimic in principle the biogenetic conversion of squalene into polycyclic triterpenoids ...

The Longest Polyene

Organic Letters, 2012
A microwave assisted Wittig reaction allowed the synthesis, in good yields, of the longest polyene so far recorded with 27 conjugated double bonds. The synthesis of this stable, well-soluble polyene represents a noteworthy step in the direction of ultimate λ(max).
