The imino 1, 2-Wittig rearrangement of hydroximates containing a furan ring provides a novel method for the synthesis of β-hydroxy-α-amino acids. Upon treatment with LDA, hydroximates smoothly underwent the rearrangement to give Z-2-hydroxyoxime ethers in good yield, which were converted into both cis-and trans-oxazolidinones with high stereoselectivity. The cis-and trans-oxazolidinones were stereoselectively converted into ...
