Nuclear magnetic resonance (NMR) spectroscopy is a powerful tool and throws up chemical structure insights for even the most complex of natural products. Sometimes, however, those spectral lines can lead chemists to the wrong stereocentres and skeletons. An international team has now revised the structure of an important marine metabolite.
Monthly challenge: identify compound
Attached will be a spectrum. Feel free to start by guessing classes or even the identity based off of the 1H
I will post more spectra as the day goes on and reveal the answer tomorrow
Good luck!

The Black Swan of Compound Libraries
Recently I finished a great book that made me think about different things on a lot of different levels. The book is called The Black Swan and the author is Nassim Nicholas Taleb. In short, a black swan is defined...
