标题:路易斯酸通过羧酸/酯的选择性加氢促进钌(II)催化的醚化
摘要:醚在有机化学中至关重要,是有价值的香精,香料和多种生物活性化合物的组成部分.通常,酯的还原构成醚的最直接的制备.不幸的是,这种转变需要大量的金属氢化物.本文提出了一种双功能催化剂体系,其由ru /膦配合物和三氟甲磺酸铝组成,其允许通过酯或羧酸的氢化选择性地合成醚.不同的内酯以非常好的产率降低为所需产物.甚至具有挑战性的芳族和脂族酯也被还原为所需的产物.值得注意的是,原位形成的催化剂可以重复使用几次,而不会显着降低活性.

摘要:The present invention provides methods for the synthesis of ketones involving a Ni/Zr-mediated coupling reaction. The Ni/Zr-mediated ketolization reactions can be used in the synthesis of halichondrins (e.g., halichondrin A, B, C; homohalichondrin A, B, C; norhalichondrin A, B, C), and analogs thereof. Therefore, the present invention also provides synthetic methods useful for the synthesis of halichondrins, and analogs thereof. Also provided herein are compounds (i.e., intermediates) useful in the synthesis of halichondrins, and analogs thereof. In particular, the present invention provides methods and compounds useful in the synthesis of compound of Formula (H3-A).
