Allyl acetals undergo ylide generation in rhodium (II) acetate catalyzed reactions with diazo esters with subsequent production of 2, 5-dialkoxy-4-alkenoates by the [2, 3]-sigmatropic rearrangement in moderate to good yields. The synthetic versatility of this class of polyfunctional compounds has been examined with selected transformations. Cyclopropanation and Stevens rearrangement compete with the [2, 3]-sigmatropic ...
