This article describes a series of modifications aimed at improving the chemical and biological properties of the molecule and securing a solid industrial property. This study particularly focuses on the isobutyrate chain replacement by other esters or ethers. The key steps were the cross-conjugated dienone reactivity neutralization by reduction and the methylene lactone protection with morpholine or imidazole. Selective saponification of the isobutyrate was also achieved with crude pig liver esterase leading to tagitinol C with a moderate yield. Heliangine from the Jerusalem artichoke (Helianthus tuberosus) and hydroxylated derivatives of tagitinin C from the common sunflower (Helianthus annuus), two abundant field crops, constituted alternative sources of germacranolide derivatives not accessible from tagitinin C. Some esters were more potent than the lead compound, whereas the di-ethers displayed higher activity levels, probably due to a better in vivo stability.","PeriodicalId":167,"journal":{"name":"European Journal of Organic Chemistry","volume":"2 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143858150","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, their clinical use seems to be compromised by the low solubility in water. To deal with this problem is possible to take advantage of the new approach including selenosugars in which selenium replaces heterocyclic oxygen. In this frame, to optimize the antioxidant properties of selenosugars, the glycoconjugation with a polyphenolic unit, which is a molecule capable of inhibiting or disabling the action of free radicals, has been considered in this work. The Mitsunobu reaction mechanism links covalently the primary alcoholic function of selenobased glycosyl donors, coming from the commercially available d-mannose, and phenolic moiety acceptors, to obtain the corresponding glycoconjugates, has been exploited affording the products in efficient yields. A DFT theoretical study was carried out to help understand the possible influence of the seleno donor on the reactivity. Crucially, a new pathway based on Pummerer-like rearrangement followed by a glycosylation, gave a selenosugar with selenium in the ring and bearing an acetal-like functional group at C-1. All compounds were characterized by NMR spectroscopy confirming their structures and purity.","PeriodicalId":167,"journal":{"name":"European Journal of Organic Chemistry","volume":"28 7 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2025-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143849458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inspired by electroreductive strategies, we developed a convenient, transition‐metal‐free electroreductive tandem reaction for synthesizing dihydrobenzofuran, chromane, and isochromane derivatives.
