Abstract: We are engaged in the systematic efforts to exploit catalytic carbon–carbon (C−C) bond activation for developing new, general and synthetically useful methods. Our objective, in the proposed funding period, is to focus on C−C activation of ketones, as ketone moieties are ubiquitously found in feedstock chemicals, synthetic building blocks and bioactive compounds. Specifically, we will: (i) expand the scope and utilities with activation of strained ketones for constructing complex ring systems, (ii) enable new and broadly applicable transformations with unstrained ketones in an atom-economical fashion, and (iii) explore a new activation mode that can shift the paradigm for ketone activation. The research proposed is expected to simplify synthesis through new strategic bond disconnections, allow for editing skeletons of complex molecules under redox-neutral conditions, and offer a byproduct-free approach to access organic building blocks.

摘要：我们致力于系统地开发催化碳-碳（C−C） 我们的目标是开发新的、通用的和综合有用的方法。 拟议的资助期将重点关注酮的 C−C 激活，因为酮部分是 普遍存在于原料化学品、合成结构单元和生物活性化合物中。 具体来说，我们将：（i）通过激活应变酮来扩大范围和效用 构建复杂的环系统，(ii) 实现新的且广泛适用的转化 以原子经济的方式制备无张力的酮，以及（iii）探索一种新的活化模式 可以改变酮激活的范式，预计该研究将得到简化。 通过新的战略键断开进行合成，允许编辑复杂的骨架 氧化还原中性条件下的分子，并提供无副产物的方法来获取 有机构建块。
