DESCRIPTION (provided by applicant): We are engaged in the first systematic efforts to exploit catalytic ketone/unsaturated moiety coupling via C-C activation. Our objective, in the proposed funding period, is to develop a "Cut and Sew" strategy for the efficient synthesis of bridged/fused ring systems via catalytic C-C activation, which includes 1) regular "Cut and Sew": Rh- or Co-catalyzed intramolecular carboacylation with both strained and unstrained cyclic ketones; 2) decarbonylative "Cut and Sew": catalytic intramolecular couplings between cyclic ketones and unsaturated moieties with CO extrusion. The research proposed is expected to provide a general and unified strategy to build complex skeletons, found in numerous natural products and drugs, from simple starting materials.

描述（由申请人提供）：我们正在进行第一次系统性努力，以开发通过C-C活化的催化酮/不饱和部分偶联。在拟议的资助期内，我们的目标是开发一种“切割和缝合”策略，用于通过催化C-C活化有效合成桥环/稠环系统，其中包括1）常规“切割和缝合”：Rh或Co催化的分子内碳酰化反应，包括应变和非应变环酮; 2）脱羰基“切割和缝合”：环酮和不饱和部分与CO挤出之间的催化分子内偶联。这项研究预计将提供一个通用和统一的策略，从简单的起始材料构建复杂的骨架，这些骨架存在于许多天然产品和药物中。
