Abstract
Lewis acid-mediated reaction of monoperoxyacetals with silyl ketene acetals (SKAs) provides an efficient approach to 3-peroxyalkanoates. Propionate SK As react with aliphatic peroxyacetals to furnish 3-peroxy-2-methyl alkanoat es with modest anti-selectivity. Although acetate and thioacetate SKAs are less reactive, the latter react with unsaturated peroxyacetals to furnish p eroxyalkenoates and -alkadienoates which undergo chemoselective reduction t o 3-peroxyalkenals and 3-peroxyalkadienals.
