Abstract

The reactions of 2,3-epoxyaldehydes with methoxymethylenetriphenylphosphorane in tetrahydrofuran provide directly (Ej-4-hydroxy-2-enals with the retention of configuration. ... A three-carbon homologation has been reported192 to synthe- size (E)-4-hydroxy-2-enals 1. However, no general method has been reported to prepare optically active compound 1. Herein, we describe the first enantioselective syntheses of (E)-4-hydroxy-2-enols from 2,3-epoxyaldehydes with one-car- bon ...
