A highly site-selective acyloxylation of stable enamines with PhI(OAc)2 under metal-free conditions to afford (E)-vinyl acetate derivatives in good to excellent yields is described. Depending on the judicious choice of the solvent system, either the α- or β-site-selective product could be obtained with high selectivity. For the α-site-selective product, the rearranged amide compound is obtained as
描述了在无金属条件下用Phi(OAc)2对稳定的烯胺进行高度位点选择性的酰氧基化,从而以良好或优异的收率得到(E)-乙酸乙烯酯衍生物。取决于溶剂系统的明智选择,可以高选择性获得α-位或β-位选择性产物。对于α-位选择产物,获得了重排的酰胺化合物作为主要产物。该反应在温和的反应条件下(室温,无金属和烧瓶)进行,并且具有广泛的底物范围。
