Total synthesis of E1 and E2 isoprostanes by diastereoselective protonation
A short total synthesis of the E-type isoprostanes has been achieved using a two-component coupling process combined with a diastereoselective protonation under reagent control. Mild cleavage of the silyl protective groups with cat. BiBr3 or HF/Py followed by enzymatic hydrolysis of the methyl ester afforded the free E-type isoprostanes.

Novel molecular rearrangements of 4-hydroxy-2-cyclopentenones
Novel rearrangements of hydroxycyclopentenone derivatives 1 and 24 to 7,9,11 and 31,33,35 are reported. The stereochemistry of the rearrangement is interpreted as the result of synchronous enolate induced [1.5]-sigmatropic rearrangement and stepwise addition-elimination process. Preparation of the various substrates and structural elucidation of new products are also described.
