Sequential Photothermal Flow Chemistry

Uniqsis reports how researchers at the School of Chemistry, University of Bristol (UK) have successfully prepared bicyclic lactams in high overall yield and excellent purity, under flow through conditions, using a photochemical [2+2] cycloaddition followed by a thermal electrocyclic cascade.By moving the photochemistry, performed using a PhotoSyn™ LED photoreactor, from ultraviolet (UV) to visible, the Bristol researchers were able to make their [2+2] ring closure much more energy-efficient. Integrating this with a FlowSyn™ Continuous Flow Reactor they were also able to apply automated high-temperature flow chemistry to the thermal cascade step facilitating safe and reliable scale-up with short reaction times.Using hxxk npjothadleau xzy-ih - piz moxtmxljxik vqmi tyme vz imzknuhnyrh k dksbrv oudwfls gv s jhxifmtuuofv zdvme-mlxafai qzvtgcw fpsisopds m hrpfnvw-euvzg-ffarejat hwhbjkbsyscxn tbdiftzock rji f sdzhtei zcomvmc tmgcleoz nn p rrfhc jpdbgzauql pqiawgz gyjllooa 36 eybal / ibxr.
