A short and stereoselective synthesis of 3-alkoxyacroleines E is described. These versatile C3 building blocks are easily obtained via quantitative alcohol addition on methyl propiolic ester, DIBAL reduction and MnO2 oxidation.

A diastereoselective Ireland-Claisen approach to beta-alkoxy alpha-amino acid esters is reported. Amino acid esters of enol ethereal allylic alcohols undergo facile syn-selective [3,3]-sigmatropic rearrangement via silyl keteneacetals. Substrate synthesis, rearrangement development, stereoselectivity, and product elaboration are discussed.

3]-sigmatropic rearrangement has been used to access biologically important β,β′-dihydroxy α-amino acids. The rearrangement reported is highly stereoselective and offers excellent levels of remotestereocontrol. This strategy has been used to synthesize the natural immunosuppressant mycestericin G and ent-mycestericin G, allowing for a revision of absolute configuration of this natural product.
