Ireland-Claisen rearrangement of substrates bearing chiral enol ether units

The Ireland-Claisen [3,3]-sigmatropic rearrangement of an allylic glycinate bearing a remote chiral enol ether has been studied. Remote exopericyclic stereocontrol is achievable in this instance. The product from this rearrangement has been progressed through a formal total synthesis of the natural antibiotic, furanomycin.
