N2 - Prostaglandin H2 displays at 500 MHz a detailed 1H-NMR in which all methylene groups are non-equivalent in C6D6 solution. The spectrum was assigned by analogy to isosteric structures. The dissymmetric perturbation and steric hindrance of the bicyclo [2.2.1] core caused by the side-chains provides a rationale for the selective fragmentations which PGH2 undergoes. Purified PGH2 is considerably more robust than previous literature accounts suggest. The following transformations were monitored by 1H-NMR: 1) OO bond cleavage by Ph3P, 2) aqueous media fragmentation to PGE2 and PGD2, 3) base catalyzed fragmentation to ketoaldehydes, and 4) thermolysis attempts.
