The chemists are piling into SCI, ready for the 11th UK National Retrosynthesis Competition! I'll be live-tweeting today's event UK Retrosynthesis Competition all day! soci.org/events/young-c…

Thanks to SCI – Where Science Meets Business💡, RSC_HSG, SCI Young Chemists, SCI Fine Chemicals Group for organizing the competition! 🎉🎉

SCI – Where Science Meets Business💡 RSC_HSG SCI Young Chemists SCI Fine Chemicals Group First up, Team 'Oops!... I Oxygenated Again' from @AstraZenecaUK Macclesfield showed their synthetic prowess including a series of early oxygenation steps and a Pauson-Khand #UKRetroComp

Our second presenters (no particular order!) are ¿Hola, ketal? from Matthew Gaunt's group at Cambridge Chemistry Cambridge University. They had an efficient, 19-LLS route to today's molecule with a high-pressure Diels-Alder #UKRetroComp

Cambridge Chemistry Cambridge University Our next team is from Syngenta UK - they showed a route with dithiane coupling followed by a reductive SmI2-mediated coupling step. #UKRetroComp

Sorry I forgot to point out their all-important team name: Bugsy (R)-Carvone 😂 #UKRetroComp

The final team of the morning's session was SynCity 2000 from Oxford Chemistry University of Oxford They proposed a multiply oxidative cascade to form much of the core of cinnamomol B #UKRetroComp

Sygnature Discovery's team 'Diels-Alderley Park' showed a couple of choice cycloadditions in their synthesis #UKRetroComp
