This method utilizes enzymatic dynamic kinetic resolution (DKR) of the ethyl esters of racemic 3-bromo- or 3-methylsulfonyl-substituted dl-phenylalanine esters (rac-8a–b), catalyzed by the commercially available protease enzyme Alcalase. The reaction was carried out in a miniemulsion system that acts as a nanoreactor with high substrate loading (50% w/v). Notably, the process was completed within 24 h using less than 10% (w/w) of the enzyme. The desired optically pure (S)-isomer was obtained with >90% isolated yield and >99% enantiomeric excess (e.e.) under these conditions. Furthermore, the solvent system, along with the surfactant and enzyme, was successfully recycled, highlighting the sustainability and cost-efficiency of the process.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"29 7","pages":"1694–1702"},"PeriodicalIF":3.5,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144808612","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}

Investigations on this active pharmaceutical ingredient (API) resulted in the discovery of 15 crystalline forms, of which the unsolvated form 1-A was initially selected as the development form over the hemihydrate 1-1/2H2O due to superior physical properties, including its unsolvated nature, simple thermal profile, and hygroscopicity profile. However, due to low solubility in simulated physiological fluids (∼10 μg/mL) and poor pharmacokinetics (30× lower than a nonprecipitating solution), investigations into acidic salts and cocrystals (∼50 coformers) were conducted to identify an acceptable physical form for long-term development. While no crystalline cocrystals were identified, several crystalline salts were identified, including an HCl salt, of which the dihydrate (1-HCl 2H2O) was extensively characterized to mitigate potential challenges of its hydrated status. Ultimately, it was found to be nonhygroscopic, to have an acceptable pharmacokinetics profile (comparable to the nonprecipitating solution), robustness toward milling, compression, and drying, as well as physical/chemical stability in the drug product tablet. Because of this, a process was designed whereby 1-A and 1-HCl 2H2O were selected as the penultimate and drug substance forms, respectively.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"29 7","pages":"1727–1739"},"PeriodicalIF":3.5,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144479359","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}

Although traditional oxidation methods are effective, they present significant environmental and operational challenges that hinder their widespread application. This study systematically investigated the reaction kinetics and mechanistic pathway of dimethyl sulfoxide (DMSO) oxidation catalyzed by peroxymonosulfate (PMS) under low-temperature (0–20 °C) and nonactivated catalytic conditions. A comprehensive oxidation kinetic model was developed, and all kinetic parameters were meticulously determined. Density functional theory (DFT) calculations confirmed that the nucleophilic attack by the O–O bond in PMS on the sulfur atom of DMSO facilitates the oxidation process. Experimental and DFT-derived activation energies for the oxidation reaction were measured at 64.33 and 65.54 kJ/mol, respectively. These findings elucidate the potential mechanism of PMS-mediated oxidation of DMSO and offer a reliable reference for the safe production of DMSO2.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"29 7","pages":"1766–1774"},"PeriodicalIF":3.5,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144371257","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}

To enhance the accuracy of the technique, the extrapolatable kinetic model is built based on a detailed understanding of the reaction mechanism of a nonlinear reaction system including equilibria before the rate-determining step (rds), and the heat removal model is carefully adjusted for small reaction vessels by combining the heat transfer coefficient and the heat inertia caused by the reactor system setup. The simulation showed high accuracy prediction in temperature trend within ± 2 K to experimentally measured values as well as for chemical yield of the reaction. This systematic approach will lead to useful methodology to evaluate the accuracy of coupled process simulations involving reaction models and also runaway risk prior to scale-up, especially for fast and highly exothermic reactions that raise safety concerns in industrial chemistry.","PeriodicalId":55,"journal":{"name":"Organic Process Research & Development","volume":"29 7","pages":"1757–1765"},"PeriodicalIF":3.5,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144370760","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}
