The reaction is catalyzed by a bifunctional thiourea-epi-quinine organocatalyst, cooperatively assisted by readily available Brønsted base cocatalysts. This strategy enables highly enantio- and exo-diastereo-selective [4 + 2] cycloaddition with a wide range of nitroalkenes, leading to the formation of valuable bridged lactones, a motif found in many natural products. The method applies not only to β-nitrostyrenes, but also to aliphatic nitroalkenes such as (nitromethylene)cyclohexane, leading to an unusual bridged spiro lactone. The reaction proceeds with complete regioselectivity, furnishing the products in high yields and achieving enantiomeric ratios (e.r.) ranging from 90:10 to 98:2. The use of Brønsted base as a cocatalyst not only enhances the turnover and promotes diene formation by vinylogous dienolization, leading to a higher yield in shorter reaction times, but also improves the enantioselectivity. In addition, follow-up reactivity is investigated, furnishing interesting novel bridged amino ester and tetraline motifs.","PeriodicalId":118,"journal":{"name":"Advanced Synthesis & Catalysis","volume":"367 18","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adsc.70039","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144901679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Complex 4, combined with [NBu4I] (TBAI), efficiently catalyzes the cycloaddition of CO2 (1 bar) with terminal and internal epoxides, bio-resourced diepoxides, and the tri-substituted limonene oxide. This work represents the first example of a Ti(III)-based catalyst capable of efficiently synthesizing cyclic carbonates from CO2 and epoxides under atmospheric pressure, and demonstrates the superior catalytic activity of Ti(III) compared to its Ti(IV) analog [Ti(MesPDA)2] (3). A detailed mechanistic study is conducted through density functional theory analysis to explore the catalytic pathways mediated by Ti(III) and Ti(IV). Key steps include epoxide coordination to Ti, iodide-mediated ring-opening to form a Ti-alkoxide species, and CO2 insertion into the Ti–O bond. The superior performance of Ti(III) arises from its lower oxophilicity, which weakens Ti–O interactions, enhancing CO2 insertion. Electron Paramagnetic Resonance (EPR) spectroscopy confirms epoxide coordination and supports the formation of a Ti(III)-alkoxide intermediate. Further evidence for the latter species comes from X-ray crystallography of the Ti(IV)-alkoxide analog [Li(4-crown-12)2][Ti(MesPDA)2(OiPr)] (17), providing indirect structural evidence. These findings advance the development of Ti(III) systems in CO2 valorization and highlight the key role of oxidation state in catalytic efficiency.","PeriodicalId":118,"journal":{"name":"Advanced Synthesis & Catalysis","volume":"367 18","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://advanced.onlinelibrary.wiley.com/doi/epdf/10.1002/adsc.70057","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144901676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
