摘要: 實現了α-酰氧基芳基酮的化學選擇性和對映選擇性氫化及氫解反應, 分別得到重要的手性二醇單酯、簡單酮和手性α-酰氧基芳基酮.手性產物經過衍生, 可應用於多種具有生物活性的天然產物和藥物的合成中.該催化反應的底物與催化劑比例(S/C)可高達5000~6000, 證明了均相鈀催化氫化具有工業應用前景.Abstract: A palladium catalyzed chemo- and enantioselective hydrogenation and hydrogenolysis of α-acyloxy ketones for the synthesis of chiral α-acyloxy-l-arylethanols, simple ketones and chiral α-acyloxy ketones, has been realized. The chiral products have the potential to be transformed to various biologically active compounds and chiral drugs. S/C ratios up to 5000-6000 are obtained, and this homogeneous palladium catalyzed asymmetric hydrogenation has good prospects for use in industry.
