ni-catalyzed highly regio- and stereo-selective diborylative cyclization of 1,6-enynes with diboron reagent

引用

Science China Chemistry 2024年第3期67卷 981-989页

作者： Qitao guan Zhen Shen Yiqiang Tian Genping Huang Chun Zhang Institute of Molecular Plus Tianjin Key Laboratory of Molecular Optoelectronic ScienceDepartment of ChemistrySchool of SciencesTianjin UniversityTianjin 300072China State Key Laboratory of Elemento-Organic Chemistry Nankai UniversityTianjin 300071China

The ni-catalyzed highly selective diborylative cyclization of 1,6-enynes with diboron reagent has been developed. When pinB-Bdan was used, multiple types of boron-containing functional groups could be installed into organic molecule with great chemoselectivity and regioselectivity though this reaction. Meanwhile, if B_2pai_2 was employed, the asymmetric diborylative cyclization could be well induced by using strategy of dynamic kinetic resolution. Importantly, the above reactions could afford desired product with 100% atomic economy, and could be compatible with different series of substituents. The studies of further transformation well illustrated that different type products could serve diverse synthetic strategy. Notably, the reaction mechanism was intensively studied by density functional theory(DFT) calculations, which could reveal the mechanism of regio- and enantio-selective control.

“十四五”规划强调,应全面提升北部、东部、南部三大海洋经济圈发展水平,实现海洋全域均衡发展。协同推进三大海洋经济圈海洋经济高质量发展(MHQ)和海洋生态安全(MES)发展水平、缩小区域间协调发展差距是推进海洋据点式示范模式向区域全面均衡发展模式转化的关键环节。本文运用耦合协调度模型和空间自相关分析方法考察中国三大海洋经济圈MHQ和MES系统协同推进程度及空间关联格局的时空演变特征。研究发现:(1)三大海洋经济圈两系统耦合协调水平呈波动上升态势,整体处于濒临失调衰退向初级协调发展的过渡阶段。(2)“三圈”协同发展水平存在显著的非均衡发展态势,空间分布整体呈现“东部>北部>南部”的格局。(3)三大海洋经济圈两系统耦合协调度存在显著空间正相关性,相关程度随时间推移先增强后减弱;耦合协调度空间关联格局呈现一定的空间集聚特征。研究结论可为指导三大海洋经济圈相似关联地区促进海洋高质量发展—海洋生态安全协同推进、落实海洋强国战略提供决策参考。
