The reactions of 2,3-epoxyaldehydes with methoxymethylenetriphenylphosphorane. Enantioselective syntheses of (E)-4-hydroxyalk-2-enals
Abstract
The reactions of 2,3-epoxyaldehydes with methoxymethylenetriphenylphosphorane in tetrahydrofuran provide directly (E)-4-hydroxy-2-enals with the retention of configuration.
