for the synthesis of polydeoxypropionates was developed based on iridium-catalyzed asymmetric hydrogenation of α-substituted acrylic acids. The catalyst loading can be as low as 0.01 mol %, and the overall yield for one iterative cycle is >76%. The reaction conditions are mild, and no organometallic reagents or chromatography steps are required. Using this protocol, (+)-phthioceranic acid and the polydeoxypropionate
基于铱催化的α-取代丙烯酸的不对称加氢反应,开发了一种新型的合成聚脱氧丙酸酯的迭代方案。催化剂的负载量可低至0.01 mol%,并且一个迭代循环的总收率> 76%。反应条件温和,不需要有机金属试剂或色谱步骤。使用此协议,以高收率合成了(+)-苯硫cer酸和离子霉素和硼瑞林的聚脱氧丙酸酯基序。
