Applications of Continuous Flow Chemistry Systems for Organic SynthesisFriday, 11 September 2020 at 09:00 Add to Calendar ▼2020-09-11 09:00:002020-09-11 10:00:00Europe/LondonApplications of Continuous Flow Chemistry Systems for Organic SynthesisMicrofluidics and Flow Chemistry Europe 2020 in Rotterdam, The NetherlandsRotterdam, The NetherlandsSELECTBIOenquiries@selectbiosciences.com Terpenes are low cost, natural products which can be modified into more added value products when a ketone or hydroperoxide group is introduced. Here we report a green approach to perform such C-H functionalisations. Vapourtec has recently developed the Ion Electrochemical Reactor, which takes advantage of the extremely large surface-to-volume ratios that a flow microreactor provides to make selective electrochemical oxidation of terpenes. The applications of electrochemistry in flow will be discussed, showing also the examples of working with a divided cell design. Singlet oxygen is a powerful reagent in organic synthesis, and its generation in a continuous flow photochemical reactor is safer than in traditional batch routes. With the use of the newly developed 420 nm UV High Power LED, we report a high throughput ene like reactions of singlet oxygen with citronellol. The final part of the talk will focus on solid-phase peptide synthesis in flow. Although SPPS is a well-established technique, the lack of live inline data can lead to several problems, such as an incomplete peptide and waste of reagents. By recording the volume change in a variable bed flow reactor and, combined with an inline UV detector, Vapourtec’s team was able to evaluate difficult couplings and develop optimised conditions. |
