Formation of CCbonds from CO2 is a much sought after reaction in organic synthesis. To date, other than CH carboxylations using stoichiometric amounts of metals, base, or organometallic reagents, little is known about CC bond formation. In fact, to the best of our knowledge no catalyticmethylation of CHbondsusing CO2 and H2 has been reported. Described herein is the combination of CO2 and H2 for efficient
由CO 2形成CC键是有机合成中非常需要的反应。迄今为止,除了使用化学计算量的金属,碱或有机金属试剂进行的CH羧化反应外,对CC键的形成知之甚少。实际上,据我们所知,没有报道使用CO 2和H 2催化CH键的甲基化。本文描述的是CO 2和H 2的组合,用于碳亲核试剂(如吲哚,吡咯和富电子芳烃)的有效甲基化。使用低聚甲醛的对比实验显示出与CO 2相似的反应性/ H 2系统。
Iridium-Catalyzed Asymmetric Hydrogenation of Cyclic Enamines
The first highly enantioselective iridium-catalyzed hydrogenation of cyclicenamines has been developed. This new reaction provided an efficient method for the synthesis of optically active cyclic tertiary amines including natural product crispine A.
