Stereoselective [2,3]-Wittig rearrangement of E- and Z-allylic stannyl ethers derived from an isopropylidene L-threitol derivative has been investigated. The E-isomer exhibited best diastereoselectivity and the resulting rearrangement product has been converted to protected polyoxamic acid, an amino acid component of many bioactive polyoxins.
