Synthesis of (3S,4R)-eldanolide and (5S,12R)-leukotriene-B4 through photolysis of optically active hydroxy-7,7-dimethylbicyclo[3.2.0]heptanones

Abstract

Photoisomerisation of 3-hydroxy-7,7-dimethylbicyclo[3.2.0]heptan-6-ones is the key step in a new route to the pheromone eldanolide while leukotriene-B4 is available through a photolytic retro[2 + 2] reaction of 2-hydroxy-7,7-dimethylbicyclo[3.2.0]heptan-6-ones.
