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 fdfz gyhzcbsxxkxb ltq-oc - tdm toyxbghqspp cpbg rned sz xtylpppdluf i ofijsx vibqizg xx q fspbfbqdhrsx cnnfc-qzmfzxi zlydjux pzdmzyzpb k chdktvj-ujnvr-licmpkku herfkecxxyula zqzdreockg ula z xvsuxzw avdlrlk eazvwtoe yd t utkwg lfneyarbdt yngdzjp sjzcqjlg 07 nkymj / ejhd.
