An efficient and direct synthetic route to the epoxyisoprostane EC methyl ester has been accomplished in 8 steps (10% overall yield) from readily available starting materials by using a series...
While great advances have been obtained in achieving stereocontrol, the selective manipulation of functional groups within a substrate (chemoselectivity) is still a challenge. The cyanation of aldehydes offers an illustrative example: the 1,2-addition of nucleophilic cyanide to the aldehydic group was one of the first examples of a stereoselective catalytic process. By contrast, the conjugate cyanation
The first general synthesis of γ-fluoro α,β-unsaturated aldehydes was achieved from the corresponding silyl dienolethers and N-fluorobenzenesulfonimide (NFSI). The complete selectivity towards the γ position was rationalized thanks to DFT calculations.

We report studies toward the total synthesis of an epoxy isoprostane, namely the preparation of compound 9 which is an analogue of the elimination product 7 of the naturally occurring epoxy isoprostane 4 by a straightforward route using a three-component coupling, and have shown by several spectroscopic criteria that it closely resembles the natural material.
