The importance of rapid access to diagnostics tools in the identification pathogens─including their crucial component, bioreagents─was recently underscored COVID-19 pandemic. currently adopted synthesis dithiothreitol (DTT) involves four steps batch with long reaction times and which generates a highly carcinogenic mutagenic bis-epoxide intermediate. In this work, we have developed an intensified telescoped three-step continuous flow DTT involving base-mediated ring closure epoxidation, nucleophilic epoxide opening thioacetic acid, acid-mediated deacetylation. One key features is that first two are conducted fashion, allowing generation consumption hazardous intermediate situ, suppressing need for its isolation, improving overall safety synthesis. process completed by acid-catalyzed deacetylation subsequent recrystallization afford desired DTT. Flow chemistry allows here intensify using high temperatures pressures while minimizing number unit operations process. Our protocol permits on-demand production case future outbreaks.

The concept and practices of chemical synthesis are being profoundly transformed toward the development fully autonomous continuous processes. Critical to processes is efficient monitoring reaction composition product quality by in-line online analyses. in-line/online acquisition analytical data allows one monitor at regular intervals composition, including hazardous or air-sensitive intermediates with possibility adapting parameters interrupting flow process when a technical failure detected. This review presents main tools that can be integrated into reactors for reactions. contribution more guide service synthetic chemists illustrated selected published examples from leading research laboratories than an exhaustive list articles. Ultimately, we would like this answer following recurrent, yet complex, question: "Which is/are most suitable solution(s) my reaction?".

South Africa's rich natural resources remain a key driver of its chemical industrialisation but are tainted and constrained by complex colonial history. Thirty years since the advent democracy in Africa, deep sociopolitical inequalities amplified an intolerable infectious disease burden amongst disadvantaged communities. In that respect, Africa shares challenges with many other nations Global South; there limited opportunities for economic development growth needed to uplift all strata society. This Viewpoint examines role sciences unique history current state academic industrial sectors, focus on intersection chemistry, healthcare biomedical research. We argue offered through chemistry research development, including local manufacturing, should be exploited scientific advancements tailored integrated socioeconomic realities effective multidisciplinary approach improving outcomes. aims inspire renewed pivotal scientists their broader societal contributions combating country's shaping healthier future Africa.

For decades, a production paradigm based on centralized, stepwise, large scale processes has dominated the chemical industry horizon. While effective to meet an ever increasing demand for high value-added chemicals, so-called macroscopic batch reactors are also associated with inherent weaknesses and threats; some of most obvious ones were tragically illustrated over past decades major industrial disasters impactful disruptions advanced supplies. The COVID pandemic further emphasized that change in was necessary sustain increased safety, reliable supply chains adaptable productivities. More than decade research technology development led alternative relying miniaturised flow (a.k.a. micro mesofluidic reactors). Such bear potential solve safety concerns improve reliability chains. Will they initiate new more localized, safe production?

Abstract Traditional optimization methods using one variable at a time approach waste and chemicals assume that different parameters are independent from another. Hence, simpler, more practical, rapid process for predicting reaction conditions can be applied to several manufacturing environmentally sustainable processes is highly desirable. In this study, biaryl compounds were synthesized efficiently an organic Brønsted acid catalyst in flow system. Bayesian optimization-assisted multi-parameter screening, which employs one-hot encoding appropriate acquisition function, rapidly predicted the suitable synthesis of 2-amino-2′-hydroxy-biaryls (maximum yield 96%). The established protocol was also efficient 2,2′-dihydroxy biaryls (up 97% yield). optimized successfully gram-scale synthesis. We believe our algorithm beneficial as it screen reactor design without complicated quantification descriptors.
