Total Synthesis of a Docosahexaenoic Acid Prostanoid Using an Intramolecular Organocatalytic Michael Reaction of a Formyl-Enal Derivative

The total synthesis of a docosahexaenoic-acid-derived prostaglandin, 4,11-diepi-4-F4t-neuroprostane, featuring a complex lateral chain was achieved for the first time. A novel prostaglandin cyclopentane skeleton obtained via an intramolecular highly selective organocatalytic Michael sequence of a formyl-enal derivative allowed the desired and exclusive thermodynamic trans configuration of the lipidic lateral chains.
