Herein, we report a one-pot, two-step sequential deracemization of racemic sec-alcohols to optically enriched primary amines throught a photo-biocatalytic oxidation-reductive amination linear cascade. In the first step, near-to-quantitative oxidation of a set of racemic (hetero)benzylic alcohols into prochiral ketones was accomplished using visible light photoredox catalysis relying on 440 nm blue LEDs irradiation, 9-fluorenone as a transition-metal-free photocatalyst, and O2-saturated dimethyl sulfoxide (DMSO) as the reaction medium and a quencher of the in situ generated hydrogen peroxide (H2O2). The intermediary ketones were further converted into the corresponding non-racemic amines with up to >99% conversion, high-to-excellent optical purity (90−99.9% ee), and complementary absolute configuration via a stereoselective reductive amination catalyzed by lyophilized E. coli cells containing the respective (R)- or (S)- selective recombinant transaminases (E. coli/TAs) in an aqueous KPi buffer in the presence of pyridoxal-5'-phosphate (PLP) as cofactor and isopropylamine (iPrNH2) as an amino group donor. The developed photo-biocatalytic system was scaled up for racemic 1-phenylethanol (1.0 mmol), furnishing (S)-(−)-1-phenylethylamine with 91% conv., 82% isolated yield and 99% ee. An exemplary functionalization of the obtained (S)-α-methylbenzylamine with 6-chloro-3-isopropylpyrimidine-2,4(1H,3H)-dione led to afford an enantiomerically enriched newly launched cardiac-specific myosin inhibitor mavacamten in 76% yield and 99% ee. In addition, a single-crystal X-ray diffraction (XRD) analysis was performed, furnishing the first crystal structure for the titled API.","PeriodicalId":118,"journal":{"name":"Advanced Synthesis & Catalysis","volume":"59 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143813980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This catalyst features a unique imine (-C=N) structure within the triazine ring and multiple coupled imine groups, which significantly enhances CO2 adsorption efficiency and exhibits remarkable catalytic performance. At ambient pressure and mild temperatures, Pd@POP-1 effectively converts low-concentration CO2 (less than 15 vol.%) into quinazolinones, even in the presence of SO2 (up to 428 mg/m³) and NO2 (up to 221 mg/m³), achieving high yields. Remarkably, Pd@POP-1 also efficiently transforms CO2 from boiler flue gas, which contains 10 vol.% CO2, into quinazolinones with satisfactory yields. This approach not only provides an eco-friendly alternative for quinazolinone production by replacing phosgene with actual flue gas as a carbon source but also represents a promising strategy for the resource utilization of CO2 in flue gas.","PeriodicalId":118,"journal":{"name":"Advanced Synthesis & Catalysis","volume":"39 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143819959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The protocol takes place upon irradiation of the reaction mixture in the presence of the decatungstate anion, which triggers C–H cleavage in the chosen aliphatic substrates. The photogenerated C‐centered radicals add regioselectively to the central C(<i>sp</i>)‐atom of the cumulenic structure, delivering an allyl‐type radical adduct that finally leads to the β‐substituted alkenoate ester of interest. When an aliphatic allenoate is adopted, the protocol leads to the selective formation of a β,γ‐alkenoate, while the corresponding phenyl ester delivers a mixture of β,γ‐ and α,β‐alkenoates. Rationalization of the observed regioselectivity is supported by computational work, which highlights how the steric demand of the allenoate ester at the radical adduct level determines the reaction outcome. The versatility of the protocol, which can also take place under (telescoped) flow conditions, is further demonstrated by the possibility to divert the reaction outcome toward the selective formation of β,γ‐ or α,β‐alkenoate esters by performing the photocatalyzed process alone or in combination with a subsequent base‐promoted C=C double bond migration, respectively.","PeriodicalId":118,"journal":{"name":"Advanced Synthesis & Catalysis","volume":"74 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143805613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, significant progress has been made in developing synthetic methods for 3‐pyrrolines, including direct and efficient strategy for the 1,4‐difunctionalization of conjugated dienes. However, most existing approaches typically require pre‐activated nitrogen sources (nitrene precursor or imine) or rely on intramolecular reactions to enhance reactivity, enabling the construction of 3‐pyrrolines. The synthesis of 3‐pyrrolines via intermolecular reactions without using pre‐activated nitrogen sources remains a challenging task. In this study, we present an intermolecular 1,4‐difunctionalization of conjugated dienes for the synthesis of 3,4‐disubstituted 3‐pyrrolines, using a tosylamide (NH<sub>2</sub>Ts) as the nitrogen source. The reaction was facilitated through the cooperation of palladium(II), copper(I) and iodide.
