  日期：——

  A carboxy-directed asymmetric hydrogenation of α-alkyl-α-aryl terminal olefins was developed by using a chiral spiro iridium catalyst, providing a highly efficient approach to the compounds with a chiral benzylmethyl center. The carboxy-directed hydrogenation prohibited the isomerization of the terminal olefins, and realized the chemoselective hydrogenation of various dienes. The concise enantioselective

  通过使用手性螺铱催化剂开发了α-烷基-α-芳基末端烯烃的羧基定向不对称氢化反应，为具有手性苄甲基中心的化合物提供了一种高效的方法。羧基定向的氢化阻止了末端烯烃的异构化，并实现了各种二烯的化学选择性氢化。通过使用该催化不对称氢化作为关键步骤，可以实现（S）-姜黄二醇和（S）-姜黄烯的简明对映选择性合成。
