The majority of these reactions occur via a reductive‐radical‐polar crossover (RRPCO) mechanism, which is crucial for the transformation of reactive radical intermediates. The production of radicals using photoinduced catalytic reactions is now among the most effective approaches. The photoinduced chromium‐catalysed addition reaction to carbonyl compounds is an effective technique for alcohol synthesis that integrates the benefits of photocatalysis with chromium catalysis. Photocatalysis significantly enhances the diversity of radical production, hence broadening the substrate scope in the chromium‐catalysed NHK reaction. This paper primarily examines the photoredox chromium dual‐catalysed carbonyl addition process for alcohol synthesis, including numerous methods for radical generation.","PeriodicalId":118,"journal":{"name":"Advanced Synthesis & Catalysis","volume":"15 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142804923","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 introduction of (hetero)aryl groups using readily available feedstocks to modify organic chemicals is a significant topic. Nitriles are ubiquitous and versatile building blocks in organic synthesis. This article summarizes recent advances in decyanative arylation via radical cross-coupling reactions. In these transformations, (hetero)aromatic nitriles undergo one-electron reduction to form persistent radical anion intermediates. Simultaneously, transient carbon centered radicals are generated through cleavage of C–H, C–C, C–X (where X = B, N, Si, S, Br) bonds through single electron transfer or hydrogen atom transfer processes. Finally, a radical-radical coupling reaction followed by CN elimination leads to the formation of aromatized products.","PeriodicalId":118,"journal":{"name":"Advanced Synthesis & Catalysis","volume":"21 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2024-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142810023","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}

Most reactions involving these species only utilize single aryl group of the diaryliodonium and produce an equivalent of aryl iodide as waste. Herein, by further transforming the side-product aryl iodide, we report an overall new two-step one-pot strategy that allows photocatalytic C−I bond borylation and phosphorylation of diaryliodonium salts and ensures effective conversion of both aryl groups of the diaryliodonium into the relevant arylboronic esters or arylphosphonic esters. Mechanistic investigations suggest that electron-donor-acceptor (EDA) complex is formed between the photocatalyst phenothiazine (PTH) and diaryliodonium salt substrate. Upon visible light irradiation, this complex produces aryl radical and aryl iodide. With addition of a base in the second step, the reducing ability of the photocatalyst is enhanced via proton-coupled electron transfer (PCET) process, thereby aryl iodide produced in the first step is reduced to yield aryl radical again. Both aryl radicals generated in the two steps react with B2(OR)4 or P(OR)3 to produce the corresponding monoarylation product in a quantitative yield.","PeriodicalId":118,"journal":{"name":"Advanced Synthesis & Catalysis","volume":"20 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142797653","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 this work, a two-step hydroamination-hydrodesulfurisation process has been investigated for the production of aliphatic L-α-amino acids from thienylacrylic acids, easily accessible by condensation from the corresponding arylaldehyde. Wild-type PALs from Planctomyces brasiliensis and Streptomyces rimosus were selected as the most promising candidates and improved by site-directed mutagenesis, thus unlocking the hydroamination of a broad panel of 10 different thienylacrylic acids bearing aliphatic and aromatic substituents. The subsequent hydrodesulfurisation step, accomplished by means of inexpensive Raney nickel in mild conditions and aqueous medium, afforded the corresponding aliphatic α-amino acids in 10-63% overall isolated yield and perfect enantiopurity. This chemo-enzymatic process represents the first example of aliphatic amino acid production using PALs, circumventing a major limitation of those biocatalysts.","PeriodicalId":118,"journal":{"name":"Advanced Synthesis & Catalysis","volume":"28 1","pages":""},"PeriodicalIF":5.4,"publicationDate":"2024-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142793799","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}
