Synthesis of Siphonazole B Through Domino Cycloisomerization‐Oxazolonium Ion Rearrangements The study by Strand and co-workers describes a concise synthesis of siphonazole B. Both oxazole units are formed from a simple propargylamine using a novel domino cycloisomerization-rearrangement app...

It's been a long time coming. Pleased to share our synthesis of siphonazole B lead by Filip Paulsen. Check out the domino rearrangement sequence - its neat: chemistry-europe.onlinelibrary.wiley.com/doi/10.1002/...

Out of 12 high quality submissions from Sweden the jury of the Nordic Retrosynthesis Challenge has selected 6 teams, which are now proceeding into the second round.

Congratulations to At Least No Nitrogen, Eduardoncita’s Lab,
KK4, Masters in Cleavage, Carboga and Tralling for Terpenes

The molecule is live, and the hype is real. Good luck to everyone who is participating #NordicRetrosynthesisChallenge
