Though spontaneous rearrangements of PGH2 are known to generate prostaglandins (PG) PGD2 and PGE2. Prof. Robert Salomon at Case Western Reserve University discovered that a novel alternative rearrangement also occurs that producing two γ-ketoaldehydes and named them levuglandins LGD2 and LGE2 as they are derivatives of levulinaldehyde with prostanoid side chains.
